 <title>How should one compare material fatigue strength in thin film area?</title>
 <link>http://imechanica.org/node/3991</link>
 <description>&lt;p&gt;For several common electroplated materials: Ni, Cu, Au and Al, which one has strongest fatigue strength? We know the mechanical properties of thin films are different with their bulk counterparts due to the so called &amp;quot;size effect&amp;quot;, and material properties depends largely on the microstructure and processing technique. But is there some mateiral laws or guidelines for designers to choose the &amp;quot;best material&amp;quot; as for fatigue resistant? Yield limit? ultimate tensile strength? or elongation? How could one compare material candidates without doing time-consuming test?&lt;/p&gt;
