While calcium phosphate-based ceramics are currently the most widely used materials in bone repair, they generally lack tensile strength for initial load bearing. Bulk titanium is the gold standard of metallic implant materials, but does not match the mechanical properties of the surrounding bone, potentially leading to problems of fixation and bone resorption. As an alternative, nickel-titaniu...

Impact responses of rectangular composite plates with embedded shape memory alloy (SMA) wires are investigated in the present research. The plate is assumed to be placed in a thermal environment; so that in contrast to the available researches in the field, the shape memory and ferroelasticity effects have to be considered also in addition to the superelasticity. The governing equations are der...

A nonlinear shell finite element formulation for shape memory alloy applications Edoardo Artioli (Roma Tor Vergata) In the last decades, the development of efficient computational models for the nonlinear analysis of structures made of shape memory alloys (SMA) has been one of the most important research activities. The shape memory alloys (SMA) represent one of the most interesting smart mater...

TO EXAMINE BIOMECHANICAL PROPERTIES of soft biological materials such as smooth muscle, tissues secured between a force transducer and micrometer are often preconditioned by subjecting them to a protocol involving sequential stretch-release cycles while the tissue is in a relaxed (i.e., unstimulated) state (4); that is, the tissue is stretched to a longer length and then released back to the or...

Materials with nanoscale features exhibit different mechanical properties from their bulk counterparts. This holds true not only for nanostructures (surface-dominant structures such as 1D and 2D nanostructures), but also for nanostructured materials (e.g. nanocrystalline or nanotwinned materials) as well as biological materials with nanoscale components (e.g. DNAs, proteins and cells). Nanomech...

Shape memory alloys are smart materials. Due to their ability to change into a previously imprinted actual shape through the means of thermal activation, they are suitable as actuators for microsystems and, within certain limitations, macroscopic systems. To apply these smart materials to a wide range of industrial applications, a simple method of controlling the actuator effect is required. Th...
