O objetivo deste exemplo é demonstrar um processo irreversível causado pelo atrito. After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
A vertical cantilever with a square cross-section is loaded at the top by tensile pressure. A consola é feita de um material isotrópico. Calculate the deflection.
Nas duas extremidades, está fixado um bloco tridimensional de material elástico-plástico. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
