• Plasticity induced crack closure is<br />
another way of stating the effect of<br />
plastic deformation around the crack tip.<br />
• Very tough materials exhibit an<br />
interesting behavior in Charpy impacts.<br />
For high ductilities, the specimen can<br />
deform without fully breaking, with<br />
consequent enormous energies<br />
absorbed.
