Torsion of a layered composite strip

This paper examines the problem of the torsional loading of a composite strip composed of eleven layers of unidirectionally reinforced elements that are fully bonded. The shear moduli are obtained from the experimental torsional stiffnesses (T/ϕ) and data reduction techniques based on the orthotropic rectangular strip torsion model by Lekhnitskii. The stacking of laminae is also used to construct a computational model of the strip.
