OBJECTIVE To determine how axial rotation around the anatomic axis of the femur, as would occur with malrotation of a femoral fracture, affects frontal and sagittal plane alignment and knee joint orientation. DESIGN Computer-generated models of the lower extremity were constructed using standardized dimensions. To simulate a malrotated fracture, these models were rotated in the shaft around t...

Fatigue tests of single crystalline Mg–0.026 at%Ce were carried out to investigate the effects cerium on crystal orientation dependence fatigue lives. Three orientations investigated: B specimen with [1100](0001)], D [1120](1100)] and E [0001](1120)]. lives increased by addition in orientations, but decreased orientation. The additions critical resolved shear stress (CRSS) for second order pyra...

Periprosthetic fracture (PPF) of the Femur is a common complication of hip arthroplasty. With increasing rates of total hip replacements, the occurrence of periprosthetic fractures is expected to rise. These fractures are often challenging to treat effectively due the technical challenges presented with the combination of fractured bone and an unstable prosthesis. Failure of locking plate fixat...

One technique to describe the failure of mechanical structures is a phase field model for fracture. Phase models fracture consider an independent scalar variable in addition displacement [1]. The ansatz approximates crack surfaces as continuous transition zone which varies from value that indicates intact material another represents cracks. For good approximation cracks, these zones are require...

in this study the performance of clay nano-particles on the soil reinforced with polypropylene fibers (pp-fiber) has been investigated. also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. soil mixtures were modified with varying percentages of nanoclay and fibers. unconfined compressive strength (ucs), compac...
