i try to simulate a 3 points bending of a glass plate with abaqus.
force 1kN !
young modulus = 7e10 Pa
Poisson's ratio = 0.22
- the plate is square (30 cm) , thickness 8.72 mm
- i use 3D extruded solid
- for the load i can't create a line load so i replace this load by pressure in a thin surface (2mm*30cm) applied in the center of the plate
- C3D8R element type
but the results are strange:
the maximum displacement is 0.672 mm !
is that realistic ? 1kN and just 0.672 mm of central displacement ?
