From: Normal contact performance of mortise and tenon joint: theoretical analysis and numerical simulation

Method Myield /(kN·m) Error /% Mu / (kN·m) Error /% K /(kN·m/rad) Error /%
Test − 19.56 − 22.14 181.06
OC-FEM − 16.02 18.1 − 17.91 19.1 154.39 14.7
VC-FEM − 18.03 7.8 − 19.84 10.4 163.82 9.5
  1. Myield is the yielding moment of the negative loading cycles, and is calculated by the equivalent energy elasto-plastic (EEEP) method [8, 46, 47]; Mu represents ultimate moment of the negative loading cycles; K stands for the bending stiffness, which is equal to the ratio of ultimate moment to ultimate rotation angle
