Abaqus results

Hi,



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  ?



thanks for helping me ...
