Abstract
The tensile test of a multidirectional laminate of strip geometry is analysed assuming that the clamping system imposes elastic restrictions to the rotations at both ends. The problem has five redundant unknowns that are determined by applying Engesser’s second theorem. Thus, the stress field can be obtained including clamping effects. The displacement field is determined by applying Engesser’s first theorem in conjunction with the unit load method. Hygrothermal effects are also included in the analysis. A method for determining the end compliances based on longitudinal strain and out-of-plane displacement measurements is proposed. Experiments are simulated by numerical results corresponding to AS4/3501-6 carbon/epoxy composite. Finally, two examples concerning multidirectional laminates with general coupling are analysed.
