ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–479 VM210 Full displacement constraints placed upon three corners in the model midplane does not allow generation of significant reaction forces. A pure bending condition is created by the application of a pressure gradient on the faces of elements lying in the z = 0 and z = L planes. The linear gradient varies from -0.18979 on the bottom to 0.18979 on the top. σz = (Mzy) / (Ic) where σZ = stress in z-direction Mz = effective moment, z-direction y = distance from neutral surface Ic = second moment of area about the horizontal centroidal axis 1 Ic = ( W H3 ) for the rectangular ends of the block 12 Results Comparison Target ANSYS Ratio StressZ , Top (AVG) -0.1898 -0.1899 1.001 StressZ , Neutral Axis (AVG) 0 -0.0002 1.000 StressZ , Bottom Axis (AVG) 0.1898 0.1898 1.000 StressZ , Top (AVG) -0.1898 -0.1899 1.001 StressZ , Neutral Axis (AVG) 0 -0.0002 1.000 StressZ , Bottom Axis (AVG) 0.1898 0.1898 1.000 SOLID95 SOLID186 1–480 ANSYS Verification Manual .
