Common metals for stable long-term implants (e.g. stainless steel, Titanium, and Titanium alloys) are much stiffer than spongy cancellous and even stiffer than cortical bone. When bone and implant are loaded this stiffness mismatch results in stress shielding and as a consequenc…

A thermomechanical description of the martensitic phase transformation and the associated shape memory effect in polycrystalline shape memory alloys (SMAs) is presented. The rate-independent constitutive relations are derived in the stress-temperature space using a Lagrangian fo…

Utilization of precast members in bridge construction is also known as accelerated bridge construction (ABC) and may be preferable to conventional cast-in-place (CIP) method because it can significantly expedite project delivery. The design of precast member connections is criti…
