Finite element analysis (FEA) is used to predict how a model will react to forces in the real world. This analysis is a part of the product design cycle and examines the effects of forces such as heat, vibration and much more. FEA is carried out to optimize designs and understand their points of failure.
FEA and FEM
Finite element analysis (FEA) uses the practical application of a mathematical method called finite element method (FEM). It is used to model complex geometrical and irregular shapes. FEM is a way of subdividing complex geometry with unknown structural behavior into a finite number of simple geometric elements with known structural behavior, known as a FEM mesh. At the element boundaries, the displacements are equated with the neighboring elements and a matrix equation is developed. The equation is numerically solved, and you can see the results graphically using a post-processor. The results displayed show you the computed stresses, strains, and displacement that occur in your model when forces are applied.
Whether you are a design engineer or an analyst, PTC has solutions that fit your needs.
Simulation and analysis are critical to the product development process and PTC’s best in class solutions use computer power to help you ascertain how a designed component might behave in the real world.
