<p><big>Toughness and strength</big></p>
<p>Toughness is related to the area under the <a href="page.php?w=stress-strain_curve">stress-strain curve</a>. In order to be tough, a material must be both strong and ductile. For example, <a href="page.php?w=brittleness">brittle</a> materials (like ceramics) that are strong but with limited ductility are not</p><p>
