I am using the *INITIAL_STRESS_SOLID and *INITIAL_STRAIN_SOLID out of a dynain filr from a gravity analysis of the same model with linear material. What seems to happen based on the results I get is that the program takes the initial strain (converts to shear strain) and looks up the corresponding shear stress from the reference input curve, but does not scale it first. In my example I have given the reference shear strain vs stress curve for a shallow element (3.5m depth). At the bottom element (35m depth) I still only get the maximum shear stress per input reference curve. The vertical stress is correct, but it seems to adjust the horizontal stresses such that the shear stress is satisfied (I can confirm this by hand calculating the stress based on the formulas given in the manual for MAT_079). When I switch the reference input curve to the values I calculate by hand for the 35m deep element, then I get the correct stress distribution (vertical, horizontal, shear).&lt;\/p&gt;&lt;p&gt;Any idea what the reason could be that the program does not seem to scale the reference shear stress-strain curve based on the initial pressure (given by *INITIAL_STRAIN_SOLID) ?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-397018","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello Pedram and thanks for the response.
