An Elastic-Visco-Plastic Damage Model : From Theory to Application
نویسندگان
چکیده
An energy-based two-variable damage theory is applied to Bodner's model. It gives an elastic-viswplastic damage model. Some theoretical details are descnied in this paper. The parameters identification procedure is discussed and a complete set of parameters for an aluminium is presented. Numerical modelling of the laboratoly tests are used to validate the model. An industrial aeronautic rod fabrication process is simulated and some numerical results are presented in this paper.

متن کاملNonlocal Vibration Behavior of a Viscoelastic SLGS Embedded on Visco- Pasternak Foundation Under Magnetic Field
This paper is concerned with the surface and small scale effects on transverse vibration of a viscoelastic single-layered graphene sheet (SLGS) subjected to an in-plane magnetic field. The SLGS is surrounded by an elastic medium which is simulated as Visco-Pasternak foundation. In order to investigate the small scale effects, the nonlocal elasticity theory is employed due to its simplicity and ...
متن کاملSimulation of Deformation and Hot Tear Formation Using a Visco-plastic Model with Damage
A three-phase model is presented that predicts solid deformation and damage as well as melt pressure, feeding flow and shrinkage porosity during metal casting. A visco-plastic constitutive theory with damage is used to model the solid deformation. Damage created by mechanically induced voiding is used as a hot tear indicator. The absence of liquid feeding determines when damage starts to form. ...

Indentation tests can be used to characterize the mechanical properties of bone at small load/length scales offering the possibility of utilizing very small test specimens, which can be excised using minimally-invasive procedures. In addition, the need for mechanical property data from bone may be a requirement for fundamental multi-scale experiments, changes in nano- and micro-mechanical prope...
متن کاملSimulation of the Visco-Elasto-Plastic Deformation Behaviour of Short Glass Fibre Reinforced Polyphthalamides
The importance of fibre reinforced plastics continually increases due to the excellent mechanical properties, low material and manufacturing costs combined with significant weight reduction. Today, components are usually designed and calculated numerically by using finite element methods (FEM) to avoid expensive laboratory tests. These programs are based on material models including material sp...
