boundary conditions - The constraints and loads added to the boundaries of a finite element model. center-of-mass (centroid): - The origin of the coordinate axes for which the first moments are zero. constraint - A boundary condition applied to a finite element model to prevent it from moving through space. density - The mass per unit volume for a given material. displacement: - A change in the location of points on an object after it has been subjected to external loads Finite Element Analysis - An advanced computer based design analysis technique that involves subdividing an object into several small elements to determine stresses, displacements, pressure fields, thermal distributions, or electromagnetic fields. mechanical stress - Developed force applied per unit area that tries to deform an object. mesh - The series of elements and nodal points on a finite element mode
