I have a solid element (1x1x1m) and I apply 5 cm horizontal displacement to the top nodes. I fix the base nodes. When I check the shear stress diagram in ls-prepost, I do not see the mohr coulomb cap for it. I mean that according to the mohr coulomb shear strength equation, &#8220;\\tau = \\sigma * tan(\\phi) + c&#8221; where \\tau is shear strength, \\sigma is normal stress, \\phi is friction angle and \\c is soil cohesion. According to the hand calculation, when I have such a solid element, the shear strength has to be more than c, since normal stress in compression and phi are positive, but the value I get is less than that.&lt;\/p&gt;&lt;p&gt;Does anybody know what am I doing wrong?&lt;\/p&gt;&lt;p&gt;Thanks&lt;\/p&gt;&lt;p&gt;Mostafa&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394161","topic","type-topic","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=\"HiI am trying to do an element test for seeing the behavior of MAT_173 in ls-dyna.
