I would like to ask your help that I have a plate with stiffeners which are suffered compression load (bottom edge is fixed, top edge is free).
It can be seen that, with the wide plate, reaction force and stress at each node at the bottom will be different
So now I want to plot stress-strain diagram to know the value of ultimate stress. So, can anyone guide me how to show total reaction force at the bottom edge then plot the stress-strain diagram?
Material: Young’s modulus, E = 200 GPa; Poisson’s ratio m = 0.3, Reh = 690 Mpa
Plate: width x length x thickness = 300x1200x4 mm
2 Stiffener: FB 20x4 mm, 2 girder: L50x20x6
Support boundary condition:
At the bottom edge of the plate and stiffeners (A-A1): all DOFs are fixed
At the top edge of the plate and stiffeners (B-B1): there is only UX is free and equal
At the C-C1 and D-D1: fixed uz
I also attached the apdl project here, so please give me your support.
Thanks in advance
