Elastoplastic Notched Plate

Overview

The aim of this test case is to validate the following functions:

• Plastic material behaviour
• Reduced integration element type

The simulation results of SimScale were compared to the results presented in [SSNP123]. The mesh used in (A) and (C) was created with the automatic-tetrahedralization-tool on the SimScale platform. The mesh used in (B) und (D) was created locally.

Simulation Setup

Material:

• isotropic: E = 200 GPa,ν = 0.3, \(\sigma_{y}\)= 200 MPa, E_T = 1000 MPa

Constraints:

• Face AA’EE’: zero x-displacement
• Face AA’BB’: zero y-displacement
• z-displacement is fixed for all nodes
• Face DD’EE’: displacement of 0.0001 m in y-direction

Results

Comparison of the cauchy stress \(\sigma_{yy}\) along path FC. The values of the reference [SSNP123] in all figures were extracted with WebPlotDigitizer.
