Fatigue resistance of nitinol stents implanted in femoropopliteal arteries is a critical issue because their harsh biomechanical environment. Limb flexions due to daily walk expose the and, subsequently, large cyclic deformations, which may lead fatigue failure smart self-expandable stents. For first time, this paper utilised up-to-date measurements walk-induced motion human artery investigate ...

in this study, first energy absorption of axial and bending loading is considered. next, thin walled structures under oblique loading are investigated using abaqus computer simulation, where 180 different cases are simulated. simulation results of the thin walled structures under oblique loading were compared with the experimental results of nagel, and good agreement was perceived. simulation r...

STUDY DESIGN A nondestructive biomechanical investigation among five anterior spinal instrumentation systems for scoliosis. OBJECTIVES The purpose of this study is to analyze the static and dynamic biomechanical stability of five different systems. SUMMARY OF BACKGROUND DATA Although a variety of anterior spinal instrumentation systems for scoliosis are available, very few attempts have bee...

Abstract Normal walking is the most action impose on the skeleton structure. The microarchitecture of trabecular bone plays an important role respect to mechanical properties. Analyse the fatigue behaviour of the trabecular bone respect to physiological activity (Normal Walking), subjected to combination of axial compression and torsional (multi-axial) load counted as the main aim of this study...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
