PURPOSE To assess the effects of positioning and notching of resurfaced femurs on the mechanical strength of third-generation saw bone (TGSB) femurs using an in vitro analogue bone model. METHODS 30 TGSB femurs were equally divided into 6 resurfaced femur groups (intact, anatomic, varus, valgus, anatomically notched, and valgus notched) for testing the load to failure, stiffness, and total en...

A tensile split Hopkinson bar apparatus is developed for testing high strain rate behavior of glass-filled epoxy. The apparatus uses a specimen gripping configuration which does not require fastening and/or gluing and can be readily used for castable materials. Details of the experimental setup, design of grips and specimen, specimen preparation method, benchmark experiments, and tensile respon...

In this research, the Stewart-Cazacu micromechanics coupled damage model is extended and validated adding nucleation coalescence models as new mechanisms. The Ti–6Al–4V titanium alloy chosen a suitable hcp ductile material to be modeled using law. characterization of evolution in addressed throughout quasi-static experimental campaign. Damage relies on situ X-ray tomography data scanning electr...

background and aims. adding further fillers to dental resins may enhance their physical characteristics. the aim of this study was to evaluate the tensile strength of heat-curing acrylic resin reinforced by tio2 nanoparticles added into the resin matrix. materials and methods. commercially available tio2 nanoparticles were obtained and characterized using x-ray diffraction (xrd) and scanning ele...
