Normaly, the weak form is derived from equilibrium at a reference configuration or differential of 1st piola-kirchoff stress tensor. In case, we have 10 steps of load increment, is it necessary to update nodal position or nodal coordinate for each step??. I am using newton-raphson method. &nbsp; </p> <p> &nbsp; </p> <p> best regards, </p> <p> sugeng </p> <p> &nbsp; </p> <br class="clear" /> http://www.imechanica.org/node/5703#comments Sun, 21 Jun 2009 23:49:53 -0400 Sugeng Waluyo 5703 at http://www.imechanica.org
