... solutions to be obtained for complex mathematical and engineering problems. It is a technique that relies on creating a geometric mathematical model of the structure out of discrete or finite numbers of individual nodes and elements. Displacement functions are assumed that allow displacements throughout...

.... With the help of finite element modeling, they analyzed the material as well as the design and in-service application of the mold. They discovered that overconstraining the mold, while it was in service, caused excessive thermal stresses which accelerated crack initiation and propagation. Investigators also...
