Failure Strength of Nonlinearly Elastic Composite Laminates Containing a Pin Loaded Hole

摘要: A method is presented for calculating the failure strengths and modes of composite laminates containing a pin loaded hole materials exhibiting nonlinearly elastic behavior. The analysis follows that proposed by Chang, Scott, Springer linearly composites with two notable exceptions: a) shear stress-shear strain relation in each ply taken to be nonlinear form Hahn Tsai, b) Yamada-Sun criterion modified include effects. Numerical results, generated using finite element scheme, were compared data. These comparisons show behavior present provides more accurately than previous employing linear stress-strain analysis.
