Abstract

The mechanical behaviour of a joint made from two dissimilar materials is determined in part by the transfer of stress across the interface between the components. A technique involving a shear lag analysis and pull-out experiments on stainless steel rods which have been embedded in a surgical acrylic bone “cement” has been used to evaluate the shear strength and shear modulus of a stainless steel-acrylic bone “cement” interface. The interfacial shear strength is then compared with a theoretical estimation of the shear stresses acting upon a femoral hip prosthesis-acrylic bone “cement” interface. Trapped blood between the stainless steel and acrylic bone “cement” was found to decrease the shear strength and shear modulus of the interface significantly.
