(c) (d) Fig. 2: (2 , 2 ) In-plane displacements , (2 ) transverse displacement , and (2 ) transverse shear stress as obtained from integration of equilibrium equations for the symmetric angle-ply five-layer sandwich plate for ( /ℎ = 4) Each of these numerical problems as shown above will provide valuable insights into the mechanical behaviour and performance of the laminate under different layer-stacking configurations . , and represents the stresses obtained by integrating of equilibrium equations while , and are obtained from the constitutive equations. 3.6. Problem.3: Numerical examples on buckling of anti-symmetric cross-ply and anti-symmetric angle-ply laminated plates ( =1 ) A simply supported laminated anti-symmetric cross-ply and anti-symmetric angle-ply square plate are adopted. The size of the plate model: length of side is = 1.2 , and thickness are varied from 1 to 100. The plate is subjected to uniaxial compressive load. The material constants are, 1 = 25 , 2 = 1 , 3 = 1 ; 12 = 0.5 ; 13 = 0.5 ; 23 = 0.2 ; 12 =0.25 ; 13 =0.25 ; 23 =0.25 ; 3.4.1. Results for buckling of plates with the anti-symmetric cross-ply and anti-symmetric angle-ply stacking sequence having ( /ℎ = 4)
