Consider the two loading cases below. For each case, sketch the directions of the l'oads, the resulting axial strain distribution Ex through the thickness, and the axial stress distribution ax through the thickness for the laminate

3)  
a) From the Tsai-Hill Criterion at the failure surface we know that 
(σ1^2/SL^2)-(σ1*σ2/ SL^2)+ (σ2^2/ST^2)+(τ12^2/SLT^2) = 1……………….(1) 
Now for the off-axis uniaxial loading the stresses can be related with the applied stress σx as 
σ1=σx*cos2θ 
σ2=σx*sin2θ 
τ12= - σx*si nθcosθ 
Now putting the above in eq.
