| In this paper, we describe models and algorithms designed to produce eecient and physically consistent dynamic simulations. These models and algorithms have been implemented in a unique framework, modeling both deformations and contacts through visco-elastic relations. Since this model of interaction (known as \penalty based") is much debated, we present it in detail. Indeed, the \penalty" ba...

The evolution of polymer welding time to join the interface thermoplastic Polyetherketoneketone (PEKK) matrix composites was characterized. Using a creep-recovery test protocol analyse rheological behavior, it shown that for temperatures above melting point (T>360°C), visco-elastic relaxation increases exponentially with time–indicating crosslinking or branching. To confirm is proportional heal...

In a system with hysteresis, the system response lags the excitation [16, 21] — for any excitation [10]. Hysteretic behavior is commonly depicted as loops in graphs (2D plots) of periodic (oscillatory) output vs. periodic input. In rate-dependent hysteresis, the size and shape of the hysteresis loop changes with the rate or frequency of the input. If the loop collapses to a function (e.g., a cu...

An analysis of radiation and soret effect on visco-elastic mhd oscillatory flow with heat and mass transfer through a porous medium bounded by two infinite horizontal parallel porous plates in presence of chemical reaction and a heat source has been presented when one plate is kept at rest while the other is oscillating in its own plane. The fluid is considered to be non-Newtonian characterized...

This paper introduces a methodology to simulate the dynamics of deformable visco-elastic 3-dimensional bodies in real-time for haptic interaction. The method is based upon a nite element approach. The central idea in this scheme is to reduce the computation required in regions which are to the periphery of the region of interaction between the virtual haptic device and the virtual body. This is...

In order to solve the elastic wave equation in heterogeneous media with arbitrary high order accuracy in space on unstructured meshes, a nodal Discontinuous Galerkin Finite Element Method (DG-FEM) is presented, which combines the geometrical flexibility of the Finite Element Method and strongly nonlinear wave simulation capability of the Finite Volume Method. The equations of nonlinear elastody...

This paper deals with the fundamental differences between industrial and paving-grade bituminous binders. The is presented in two main sections: 1) a review of materials’ colloidal structure required properties for paving applications; 2) wide range experimental tests which binders were studied compared. In this research, 160/220 bitumen was compared to same penetration lower penetration, 70/10...
