Hello everyone,
i created a 3-point-bending-test with a composite laminate of 6 plies. The loadstep is a nonlinear static analysis.
The Stamp moves constantly and deformes the laminate, but at the end of the simulation the result of the disp-force curve is a linear curve. The force is measured at the Stamp-knot and the displacement at the center of the top laminate-surface.
I think i have to enable the plastic behavior of the composite, but i dont know how.
-Do i have to enable the MATF-Card in the MAT8-card and if yes, which values i have to type in?
-Do i have to to enable a dmgevo-card and if yes how can i conntect it with the mat8-card?
The curve should look like the blue curve in the left top picture: https://www.researchgate.net/profile/Eyuep-Basaran/publication/340004105/figure/fig5/AS:871103547310081@1584698678081 /Compression-force-displacement-graphs-of-the-composites.png
The
MAT-Card-Images are also attached. Cfk (PCOMPP) and Matrix (PSOLID).
Would be really nice if someone could help me! Thanks in advance!
King regards
Al
