How to model contact that only transfers axial compression but no axial tension and shear in Plaxis?https://communities.bentley.com/products/geotech-analysis/f/forum/224812/how-to-model-contact-that-only-transfers-axial-compression-but-no-axial-tension-and-shear-in-plaxisHi guys, How can I model this type of contact between surfaces?

Because axial compression is along one of the in-plane axis, so that won&#39;t be a contact stress. <br />The easiest solution would be to use an interface and assign the interface its own material set. Specify a very low strength in the interface material set (theoretically you would like it to be zero, but numerically that won&#39;t work - so give it a low cohesion and a zero friction angle) to limit the shear to almost zero and with the default tension cut-off option of the material normal tension can be set to zero.</p> <p>With kind regards,</p> <p>Dennis Waterman</p><div style="clear:both;"></div>
