Test Case
A multibody of four bars connected end to end has one of the end faces fixed, and a pressure is applied to the opposite face as shown in the problem sketch. The multibody is used to nullify the numerical noise near the contact regions. Find the maximum equivalent stress for the whole multibody as well as the safety factor for each part using the maximum equivalent stress theory with tensile yield limit.
This test case is also solved using Ansys Mechanical. See VM-WB-MECH-009.
