Structural mechanics

Structural mechanics

Structural mechanics or structures can be mechanical, for calculations in performance or for the performance analysis of existing structures, assumptions, deflections and internal forces or stress (stress equivalent) structures. It is a subset of structural analysis. Structural mechanics of structural mechanics need analysis, the geometric representation of the structure and the terms of support, and the inputs' information as input to the property. Output quantity support may include response, pressure, and displacements. Advanced Structural Mechanics may include the effect of stability and non-linear behavior.

Mechanical machining of the structure is a field in the field of mechanical studies that investigates the behavior of structures in mechanical loads such as a beam, hanging of a column, a shuffle bait, a thin shell wrapper, and a bridge vibration.
Analysis has three perspectives: energy method, flexibility method or direct hardness method, which is then developed into a limited material method and plastic analysis method.
Structural supervision One of the basic departments of engineering. About the structure of structure and stability analyses of structures, each member, distortion, destruction and so on, such as buildings, bridges, bridges, airframes, hulls, etc. Bimas (arches), pillars, trusses, ramens, arches, and similar three-dimensional structures are also important as structural structures of wood. It is related to component dynamics, elasticity theory, vibration theory, and closely related to it.

Deformable, embroidered, displacement and destruction research under the difficult arising external pressure factors of the mechanical branch of the hard mechanics. Difficult mechanics, previously, made up of applications are mechanical hard mechanics wide. The principles of different structures of water and deformable methods of calculation are difficult, there are difficult mechanics applications that can be seen in their design and accounting.

Short introduction

The study of mechanics of solid mechanics solids is the mechanical properties of mechanical mechanics, the main research in the role of external solid, temperature and deformation performance, a branch of continuing mechanics. Common materials include mechanics, elasticity, flexibility mechanics. Solid Mechanics Extensively used to describe pressure tensors, hugs, and relationships between them.

In solid mechanics, the linear material model is widely used, but many materials, the linear model reaches more extensive new content and the main content application limit is not non-linear features, with their application.

The theory before solid mechanics, strong structural mechanics of a branch, is a mechanical mechanism, it is mainly deformable in the study of particle roles (such as load, temperature, humidity, etc.) in the external particle generated, deformable difficult, regular exercise, stress, hug, and damage.

Both elastic mechanics problems have solid content, plastic problems; There are both linear problems in linear problems; Research before hard mechanics, and more commonly assumed a homogeneous continuous medium of matter, but in recent years mechanics of enhanced compounds and stretch mechanics to expand mechanics & nbsp; & nbsp; The hardest mechanics book

The objects have small particles of big nature, solids, and various difficult mechanics problems. Shanbengdelie is well known, worried marshes and difficult mechanics. Modern engineering, whether it is applied to aircraft, ships, tanks, or houses, bridges, dams, nuclear reactors as well as family furniture, structural design, and accounting principles and difficult computational methods.

Due to the rapid development of a wide range of projects and science and technology, the development of hard mechanics is on the other hand, on the basis of modern engineering and new theories and methods are adapted, on the other hand, the tradition of the useful classical theory is on the one hand.

According to the hard mechanical shape of the object, the rod, plate, and shell, space body, thin-walled bars can be divided into four parts. Thin-walled members are not the same order of long magnificent size solids. Waiting for aircraft, ship, and construction engineering structures are widely used in thin-walled bars.

A brief history

Original

History The hard mechanics can be found back in 1638, Italian scientist Galileo has proposed the formula for calculating the strength of the first beam. This instrument is considered at the beginning of the development mechanics of development. The conclusions are not entirely accurate, so at that time, also, using rigid body mechanics calculation methods. Later British scientist and published in Hook 1678; Force and deformation are proportional to & quot; Important physical law (i.e. Hooke's law), established the idea of elastic deformation. From the 17th century in the 18th century, some scholars have studied the development of elastic rod transversal curve, lateral vibration, and compression stability, elastic rod mechanical theory.

Development
At the beginning of the 19th century, the development of the industry, the design of a large-scale engineering structure, the structural mechanics will become an independent discipline. Since 1830, a metal truss has been formed. After several decades, statically limited trance graphic methods and analytical methods, foundation-trance theory solving inter-established. In the 19th century, the theoretical structure of 60 to 70 years and determining a statically unstructured formation made the calculation of Statistical Unconscious Structure Ball approach to determining the deformation power method. In the early 20th century, the framework of computational theory, simple calculation method, dynamic analysis, etc. in the framework of structural mechanics improved the stability of the complex, improving the statistically unconscious direction.

Modern mathematical resilience and complete solid & nbsp; & nbsp; Difficult mechanics

Branch
Another mechanism of tough mechanics flexibility, rising flexibility theory, slip line theory, the total plastic potential theory of flexibility and plastic limit analysis theory has appeared in various development. With the development of manufacturing, solid mechanics, computing technologies and experimental techniques have formed a new branch of research development in the field of great development, computational structural mechanics, composite materials, crack mechanics, loss mechanics, and experimental difficult mechanics.

Childhood

Far, two thousand years ago, the idea of building construction among mechanics, easy tourism and hunting equipment in BC and other ancient civilizations of the world was to start. China's Middle Kaihuang (AD 591 ~ 599 years) already has some of the basic concepts of modern rods, plates, housing design, archway arch bridge construction.

With the accumulated experience and technology accumulated in the construction of housing, the improvement of the accuracy of mankind, bridge and ship construction aspects continue to brighter success, but the primary information about energy calculation or other aspects of experience and experience is not very much handed down and handed down. However, this class of foundations laid the foundation stone of this theory, especially in the theory of advanced mechanics of advanced success or its earlier mechanical mechanics and structural mechanics for the next classified material.

Development time

The success of experimental experiments of 17th-century physics in the development of accumulation and difficult mechanics theory was ready for success. In the 18th century, this social demand in large machines manufacturing, large bridges, and big factories, building a driving force for the development of hard mechanics.
