Re compute given Exercise adjusting for in-situ strength, assuming the transition thickness for this material is t_t = 0.6 mm.

Exercise

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

E₁= 137.8 GPa

E₂ = 10 GPa

G₁₂= 5.236 GPa

v₁₂ = 0.3

F_1t = 826.8 MPa

F_1c = 482.3 MPa

F_2t = F_2c= 68.9 MPa

F₆ = 241.15 MPA

and thickness t_k = 0.127 mm, subject to N_x = N= = 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.
