The Double Punch test, an indirect traction test, is simulated numerically considering two different models (the nonlocal Mazars damage model and an heuristic crack model with joint elements). The test was designed to measure indirectly the tensile strength of concrete, hence, through these two numerical models, we are able to assess the tensile strength numerically. Experimental results presen...

We introduce a novel three-dimensional (3D) traction force microscopy (TFM) method motivated by the recent discovery that cells adhering on plane surfaces exert both in-plane and out-of-plane traction stresses. We measure the 3D deformation of the substratum on a thin layer near its surface, and input this information into an exact analytical solution of the elastic equilibrium equation. These ...

AC power cycling tests allow the most realistic reliability assessment by applying close to real stress device or module under test meet functional safety standards, which is highly critical for traction applications. This paper presents a comprehensive guideline and shares know-how develop 120 KVA setup high-power Silicon Carbide (SiC) modules. As of today, applications can not generate an ear...

Abstract The autotransformer (AT) neutral current ratio method is widely used for fault location in the AT traction power network. With development of high-speed electrified railways, a large number data show that relation between and distance from beginning section to point (Q–L relation) mostly nonlinear. Therefore, linear Q–L traditional always leads errors. To solve this problem, load-relat...

background: fractures of femur are among the most important causes of mortality in musculoskeletal injuries. owning to lack of adequate research to compare various techniques of fracture stabilization, there has not yet been an agreement over a protocol to utilize a specific type of splint for femoral fracture immobilization. this study was thus conducted to compare the effects of simple and tr...

Mobile Robots are used to venture through types of environments where wheel slip is a threat. Wheel slip is a hazard to mobile robots in that it introduces error in dead reckoning measurement and in some instances causes the robot to halt is forward progress. To compensate for traction loss several methods are used to determine the terrain characteristics. One of these methods is Pacejka’s Tire...
