Interlaminar failure due to mechanical and thermal stresses at the free edges of laminated plates

A model to analyse deformations and stresses in structural batteries due to electrode expansions

“…In this case, the two basic stress shapes e −φy and e −φλy coincide, hence as suggested in [10] and [13], a new initial shape for σ 22 is proposed. In particular if a characteristic equation shows repeated roots, the exponential solutions are e −φy and ye −φy .…”

“…Webber and Morton gave the algebraic conditions for the existence of solutions for simple cases such as cross ply laminates, as reported in Appendix B of [13]. The complexity of the equations for the general method however make 220 it extremely difficult to predict which conditions result in unsolvable problems.…”

“…As reported in [13] the complementary energy for a thermo-elastic laminate, with null traction and body forces, can be written in general as:…”

“…Only a few combinations have been found where the method presented a so called blind spot in the parameter space [13].…”

“…In particular the pure thermal cases reported in [13], [14] and [20] with specific ply properties have been simulated using the …”
