The present study considers an elastic-plastic contact analysis during loading-unloading of a deformable sphere with a rigid flat using finite element method. The effect of strain hardening on the contact behavior of a nonadhesive frictionless elastic-plastic contact is analyzed using commercial finite element software ANSYS. To study the strain hardening effect different values of tangent modu...

In India Co-60 is the isotope presently being used for medical applications. It needs frequent replacement because of its short half life (5.27 Years) resulting in multiple handling, transportation and loadingunloading operations. Further, in Indian scenario, production of Co-60 also leads to reactivity losses and in turn revenue losses to the nuclear power reactors. However, Cs-137, the major ...

Cohesive laws describe the resistance to incipient separation of material surfaces. A cohesive finite element is formulated on the basis of a particular cohesive law. Cohesive elements are placed at the boundary between adjacent standard volume finite elements to model fatigue damage that leads to fracture at the separation of the element boundaries per the cohesive law. In this work, a cohesiv...

Vehicular injury is one of the main reasons for traumatic injuries. Finite Element Human Body Models (FEHBM) have become very popular to assess car crashes and the subsequent injuries. It provides the possibility to predict stress and strain values in tissue level by representing anatomical structures in details. An essential requirement for the FEHBM is to exhibit human-life response, i.e. bei...

ELASTIC HYSTERESIS IS A PROPERTY of tendon and describes the energy dissipated due to material viscosity. The amount of tendon hysteresis is important for efficiency of locomotion. Higher hysteresis is associated with greater energy dissipation as heat, and thus less energy can be recoiled to propel our movements. Classical papers report hysteresis of 7% in the plantaris tendon of sheep (9) and...
