Numerical modeling of lead material : Cyclic shear stress-strain relationship in large strain region

Abstract

This paper shows shear stress-strain relation of lead material to develop a numerical model. The specimens were composed of circumferential lead and two steel flanges. Vertical displacement and rotation of the upper and bottom flanges were constrained and horizontal displacements were applied to the upper flange of the specimens by a dynamic biaxial test device. The loading test results show the shear stress-strain relation in small and large strain and effect of the height-diameter ratio f specimens on stress-strain curve.
