Unformatted text preview: t = 0.02m, h = 0.01m. The crack growth rate is given by 11 3.59 1.6 10 ( ) m/cycle I da K dN in which K I is in MPam. Find the number of cycles to failure (at which the crack becomes unstable under the load P max ). Assume that the plane strain condition exists. 3. The truss structure consists of two bars connected by a pin-joint (which allows free rotation of the bars). The other ends of the bars are hinged as shown in the figure. A weight W is hung at the joint. Find the maximum weight the truss can sustain before buckling occurs....
