<span>Dear<br />
Dr. Hutchinson,</span>
</p>
<p>
<span>The<br />
fracture energy can be calculated experimentally from the area under P-w curve divided<br />
by ligament length. This was calculated by many researchers by taking w at the<br />
crack mouth; however, according to my understanding, from the definition of<br />
fracture energy, w should be calculated at the crack tip.</span>
</p>
<p>
<span>I<br />
would appreciate if you could help me in this regards</span>
</p>
<p>
Thank you
</p>

<div class="field field-name-comment-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>I agree with Rui. Large-scale yielding problem is explained very nicely in this lecture note. Despite the current research activities on small-scale plasticity mechanisms, many materials scientists are still inclined to understand it from continuum mechanics.</p>

<div class="field field-name-comment-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p>One question I am frequently encountered is: how do we analyze fracture with large scale plastic deformation, theoretically and numerically? I learnt a little from Zhigang's class on HRR solution, Dugdale-Barenbllat's cohesive mode, etc. It seems not enough to solve any practical problems. I will try to learn more from this notes. Thank you, John! </p>
