Abstract : Solutions for the elastic torsion of sandwich strips having triangular, rectangular, or trapezoidal cross sections are presented analytically in terms of suitable design parameters. Data obtained from resulting expressions are presented in a series of design curves for normalized values of torsional stiffness and maximum facing and core shear stresses. The analysis is based on the Saint Venant theory of torsion. The sandwich facings are idealized as identical, thin, isotropic membranes, while the core's elastic behavior is characterized by a single transverse modulus of rigidity. (Author-PL)
