Predicting the contact mechanical response for various types of surfaces is and has long been a subject, where many researchers have made valuable contributions. This because surface topography tremendous impact on tribological performance applications. The mechanics problem can be solved in ways, with less accurate but fast asperity-based models one end to highly not as rigorous numerical meth...

The role of heart disease in increasing worldwide death and the limited availability of organs for transplantation have encouraged multiple strategies to fabricate functional and implantable constructs. One of these strategies is to develop a biologically similar heart tissue scaffold, in which two types of fiber and hydrogel are commonly used. Toward this goal, taking advantage of both hydroge...

Forging dies at high temperatures are under contact pressure, variable mechanical loads and thermal shock, furthermore they should withstand wear and friction in a high level. So, in order to increase die life, the selection of die material, coating and hardness is essential. In this review, various methods used for die life enhancement such as carbide coating, using the super alloy stellite 6 ...

Thermal management has become a promising field in recent years due to the limitation of energy resources and global warming. An important topic improving efficiency thermal utilization is how control flows heat, rectifiers, such as transistor, have been proposed units for modulating flow heat. In this work, reconfigurable non-contact transistor with two-dimensional grating introduced. The cons...

The paper refers to the influence of corrosion on installation and development thermos - mechanical contact fatigue metallic elements. analysis takes into account thermal Jacq effect position origin a crack following fatigue. Here are presents some aspects concerning wear links these two kinds in common deterioration layer. Schematic draw test stand is presented with main component elements ano...
