I used static analysis with Visco-elastic HMA properties for dual tire loading condition. I am interested in the displacement at the center of the dual tire load and at a lateral distance of 18 inch along the central line. The 3D-Move calculated displacements are erratic (too high or negative) at these locations.
However, when i tried the same structure with linear elastic properties, the displacements are reasonable (8.6mil). I like to know if anybody else have similar problems, or its me doing something wrong.
