![]() Strain-displacement relations, which measure the deformation that the design experiences under any given external impacts.Equilibrium equations, which find when the opposing forces or influences are balanced.This test helps developers understand the product's performance when dealing with various ground frequencies and vibrations, ensuring a sturdy location for the final structure.įinite element analysis are based on principles that include boundary conditions, such as forces and pressures, as well as three governing equations: This form of finite element analysis also allows users to adjust for vibrations throughout the design stage, thus creating a strong final product. ![]() Every object vibrates at a frequency, so it is important to use modal analysis to test how disruptive external vibrations affect the product's structure. This test explores variations in temperature and how it affects the design structure. ![]() The test maintains that any structure that is sound on a small scale will be able to handle the same interactions with the full-scale structure and produce the same results. This type of FEA analyzes a scaled model based on proportions. Various different types of tests are used during finite element analysis, such as: Now, it is common to find virtual testing and design optimization integrated into the product development cycle to improve the product quality and reduce the time it takes to enter the market. Finite element analysis software emerged in the 1970s with programs such as Abaqus, Adina and Ansys. Using finite element analysis can reduce the number of physical prototypes created and experiments performed while also optimizing all components during the design phase. However, it is important to note that FEA only provides an approximate solution it is a numerical approach to finding the real results of partial differential equations. Finite element analysis emerged as a way for computers to solve both linear and nonlinear PDEs. The FEM creates a set of algebraic equations which engineers, developers and other designers can use to perform finite element analysis.įrequently, the physical experiences of a product - such as its structural or fluid behavior and thermal transport - are described using partial differential equations (PDEs). ![]() Engineers use FEA to find vulnerabilities in their design prototypes.įEA uses the finite element method (FEM), a numerical technique that cuts the structure of an object into several pieces, or elements, and then reconnects the elements at points called nodes. Finite element analysis (FEA) is the use of calculations, models and simulations to predict and understand how an object might behave under various physical conditions. ![]()
