While the Lapidus procedure is a widely accepted technique for treatment of hallux valgus, the optimal fixation method to maintain joint stability remains controversial. The purpose of this study is to evaluate the biomechanical properties of new shape memory alloy (SMA) staples arranged in different configurations in a repeatable first tarsometatarsal arthrodesis model. Ten sawbones models of ...

Phase-field fracture simulations have been established to simulate crack propagation in solid structures. The method employs a variational framework which has proven converge Griffith' classical model for brittle fracture. Here we investigate the predictiveness of phase-field through four-point bending test mixed mode condition, and discuss possibilities perform such simulation with finite elem...

The present paper is devoted to fracture analysis of an inhomogeneous non-linear elastic beam configuration with three parallel longitudinal cracks. material continuously along the height. subjected four-point bending. behavior studied by applying J-integral approach. Solutions are obtained for For this purpose, curvature and coordinates neutral axes crack arms determined using equations equili...
