Method for calculating simulation of body by explicit finite element method, involves observing finite elements, which have distance smaller than one-dimensional stretch ahead of point i.e. point of introduction of load

摘要

The method involves observing finite elements (I, II, IV-XVI), which have a distance smaller than a one-dimensional stretch (r) ahead of a point (B) i.e. point of introduction of load. The stretch is provided with length of elapsed simulation time multiplied with sound velocity. Characteristics of the elements are calculated when nodes (1-16) of the element lie within a three-dimensional sphere, a two-dimensional circle or the stretch. Degrees of freedom of the elements are accessed when the nodes do not lie within the sphere, the circle or the stretch.
