Collision Angle

Joining of metals in explosive welding takes place as a result of their plastic deformation during a high speed collision and is usually accompanied by typical formation of waves at the interface. In welding aluminium, the weld boundary can also be straight if the speed of the contact point is νc is ≤ 1900 m/s. These welding conditions make it possible to prevent melting of the metal at the interface and increase at the same time its corrosion resistance. In this article, the effect of the dynamic collision angle on the special features of plastic flow of the metal in the vicinity of the contact boundary in welding sheets of AS5 aluminium is described.

In this work, computational and experimental studies of the process of destruction of composite firing pin of porous alloy tungsten+nickel+iron+cobalt with 10 % content of titanium tungsten carbide at high-speed collision with steel barriers. It is shown that at ballistic tests with the broad range of speeds, significant exceeding of penetration of these firing pins in steel barriers in comparison with a mass-dimensional analog of the W-Ni-Fe-90 alloy. Based on the analysis of the crater morphology and structure of the striker fragments after penetration into the barrier, the assumption of implementation of the self-sharpenings mode of the firing pin, by means of localization of plastic deformation is made that leads to decrease in the effective area of interaction and increase in depth of penetration. Modification of a mathematical model of a porous ideal elasto-plastic solid with complex structure for the description of destruction with a possibility of accounting of the adiabatic shift mechanism in the course of interaction of the firing pin and a barrier is carried out.

Haptic Simulation

Modeling the interaction between dynamic objects in a haptically enabled virtual environment requires high-speed collision detection. We present an independent comparison of two publicly available collision detection libraries, V-Clip and SWIFT++, as they perform in our assembly and disassembly simulation. Three assembly sequences, differing only by the complexity of the objects involved, are tested and compared based on speed of execution. In the process, some potentially limiting factors experienced while using these libraries are exposed.

Obvious Similarity

Red blood cells suspension was infused into the microchannel in micron-sized made of PDMS and this leaded to the collision between the red blood cells and the wall of the microchannel. The microflow video was observed and recorded with optical microscope and high-speed camera used. The visualizing of the movement and collision of red blood cells was achieved. The flow images were optimized and the values of the geometric parameters of the red blood cells at different positions were obtained. Combined with the experimental data, the fitted curves of the geometric parameters on the axis of the microchannel were achieved. Besides, the comparison among the flow characteristics for different flow rates was also completed. It turned out that the width of erythrocytes in the microchannel increased and the length decreased continuously along the flow direction, so did the elongation. Erythrocytes gradually developed into tabular shape from initial slender shape along the flow direction. Whats more, the trends of the geometric parameters at different flow rates showed obvious similarity.
