采用球形压头的数值模拟表明, 当应变硬化指数n大于0.23时, 不论屈服应变σy/E为何值, 在压入过程中所有材料的压痕周围均出现凹陷; 当n小于0.23时, 随着σy/E的增大, 材...

Roller pass is one of the key factors affecting the product quality in the retained mandrel rolling process. The metal flow condition of rolling deformation area was researched using the FEA (finite element analysis) software Marc. The influences of the pass bottom radius, the sidewall radius, the s...

Two full 3D steady mathematical models are developed by finite element method (FEM) to calculate coupled physics fields: the electro-magnetic model is built and solved first and so is the fluid motion model with the acquired electromagnetic force as source body forces in Navier-Stokes equations. Eff...
