<strong>The</strong> Shear locking Phenomenon<br />
This occurs when significant bending is present. It is owed to <strong>the</strong> use<br />
<strong>of</strong> linear shape functions that cannot accurately model <strong>the</strong> curvature<br />
that is present in <strong>the</strong> actual material under bending condition.<br />
Instead, a shear stress is introduced which causes <strong>the</strong> element to<br />
reach equilibrium conditions <strong>for</strong> smaller displacements that <strong>the</strong> real<br />
ones.<br />
<strong>The</strong> element <strong>the</strong>re<strong>for</strong>e appears stiffer.<br />
