SS-V: 1070 Plate with a Hole

Test No. VS08 Find the maximum stress of a plate with a hole.

Definition



Figure 1.

Due to symmetry, only ¼ section was analyzed (Figure 1).

The units are SI.

Sliding constraints applied to the left, back, and bottom faces.

The load is 5000N applied to the right face.*
