Static Analysis (Elasticity)

Static Analysis (Elasticity)

This analysis uses the data of tutorial/01_elastic_hinge.

Analysis target

The target of this analysis is a hinge part whose shape and mesh data are shown in Figs. 4.1.1 and 4.1.2, respectively. The mesh is a tetrahedral secondary element with 49871 elements and 84056 nodes.

Analysis contents

In this stress analysis, the displacement of the constrained surface shown in Fig. 4.1.1 is restrained, and a concentrated load is applied to the forced surface. The analysis control data are presented below.
