Table 7. In-plane average stresses for the boundary-constrained Cu mesh (ΔT = 25°C) obtained from slopes of regression-fitted lines to the data shown in Fig. 10.
The stress values for the equivalent isotropic slab were computed using equation (14) with bulk elastic moduli, yielding σ11 = σ22 = −74 MPa.
