Solid can bear a large magnitude of force or stress, the analysis of solids under the action of force or stress is called Solid Mechanics. The study is applicable to every object which can be of any material thus it can be considered a vast domain. An object can be classified as a solid only when it can bear a significant amount of force. Solid mechanics are divided into a static and dynamic category. As their name implies, static deals with stationary objects while the dynamic category deals with moving objects. The application of force on an object will cause it to change its shape, the amount of change is known as Strain. According to law, Strain is commensurate to Stress. There are few terminologies associated with Solid Mechanics such as Elasticity and Plasticity. Elasticity can be defined as the tendency of an object to return to its initial state after a force is applied to it. Few objects do not return to their original shape and position, this phenomenon is called Plasticity. A solid is called plastic if it does not return to its initial state after the application of force. It is interesting to calculate the breaking point of an object after which the applied force will fracture the object.

Finite Element Analysis is purposed to analyze and simulate the behavior of a solid mathematically under the application of a force or stress. Before initiating the analysis, the nature of elements and constraints are to be decided. The stress distribution is represented by color distribution where a red color represents stress. The motion of an object can be modeled using differential equations, FEA solves these equations to calculate the state of an object. FEA points out the weak areas in the design and suggests the improvements to be made in the design. For analysis, it is a little difficult to analyze ab object as a whole, therefore, the object is divided into numerous small equivalent objects known as Mesh, and the response of each piece is calculated and the final response is obtained by obtaining the results of all the pieces. The pieces are interconnected at a point called Node. However, the response is obtained on a few points only termed as Nodal Points, we have to approximate the response of Nodal Points on other points to get the response of the whole body. For a solid, freedom’s degree equals the number of nodes, for example, a triangular object has three number of nodes. Solid mechanics is not limited to force and strain only, a solid can be deformed by thermal effect as well, while a decrease in temperature may result in contraction as well. FEM is extended to thermal expansion as well. The expansion of a solid due to the application of heat is dependent upon the material coefficient. This expansion due to mechanical stress and thermal effect can be mathematically modeled.
