The ever-increasing increase in human needs and the effort to fulfill them has led to the creation of new and complex problems in all scientific and technical fields, and the field of mechanical and structural engineering is no exception. In most cases, there is a need to design and analyze parts with complex geometries and properties under irregular loads, which using existing classical methods (for example, the theory of elasticity regarding stress distribution) leads to finding very complex governing equations with boundary conditions and The initial is diverse, which practically makes it impossible to solve these equations analytically. That is why various numerical methods for solving differential equations governing systems are created and are widely used today.
Depending on the type of numerical method used and the type of elements, different methods such as finite volume, finite components, etc. have been obtained. The limited differences of each of the aforementioned methods are offered to users in the form of various software. The method that is used in most solid mechanics problems is the finite element method, which can be used in the form of software such as Ansys, Abaqus, Nastran, etc.
In this project, it is intended to familiarize with CAE/ABAQUS software and analyze some examples to show the capabilities of this software. Usually, engineers and physicists describe a physical phenomenon by means of a system of ordinary or partial differential equations that are true and the boundary and initial conditions 2 that provide the appropriate range. In fact, a differential equation with required boundary and initial conditions is a complete mathematical model of a phenomenon. In order to find the distribution of the desired variables whose relationship is expressed in the differential form by the governing equation, the mentioned equation must be solved so that the numerical values of each related quantity can be obtained at desired points. But due to the fact that only the very simple forms of these equations can be solved in very simple geometric regions with analytical methods, we are facing a big problem in solving most of the governing equations analytically…
