Find the strength ratio r at the bottom surface of laminate

Reference no: EM131358092

Consider a laminate [±45] of the following material:

and thickness tk = 0.127 mm, subject to N_x - N_y= 1.0 N/mm. Determine the strength ratio R at the bottom surface of the laminate, using the following strength criteria:

(a) Maximum stress,

(b) Maximum strain,

(c) Interacting failure criterion. Do not adjust for in-situ strength. You are allowed to use a computer program to find the stresses but you must present detailed computations of the R values
