<p>Hello,</p>
<p></p>
<p>I modelled a 3-D DCB (Double Cantilever Beam) test specimen to simulate crack propagation (delamination) in <strong>composite materials</strong>.</p>
<p>To do so, I used surface <strong>cohesive properties</strong> between plates in Abaqus/Explicit, and applied a displacement at the plates tips.</p>
<p></p>
<p>When I used <strong>continuum shell elements</strong> the crack propagated as expected and the delamination occurred.</p>
<p>But when I used homogeneous<strong> solid elements</strong> (with the same properties used before), the crack did not propagate at all. </p>
<p>It seems that the continuum shell plates are much more stiff than the solid ones...</p>
<p></p>
<p><strong>Do anyone knows why this is happening?</strong></p>
<p></p>
<p>Thank you for your time and attention.</p>
<p></p>
<p>Best regards,</p>
<p></p>
