Heterogeneous incompressible fluid flows with jumps in the viscous properties are solved with the particle finite element method using continuous and discontinuous pressure fields. We show the importance of using discontinuous pressure fields to avoid errors in the incompressibility condition near the interface.

    Stress intensity factor (SIF) is an important parameter in fracture mechanics, which judges whether there is crack propagation. Many methods can be used to calculate the stress intensity factor, such as J integral, Green function method, COD field method and so on. Based on the fact that the...

    From various draw-bend friction tests with sheet metals at lubricated conditions, it has been unanimously reported that the friction coefficient increases as the pin diameter decreases. However, a proper explanation for this phenomenon has not been given yet. In those experiments, tests were...

    The bubble growth and departure at the tip of inclined glass capillary tubes in stagnant fluid is experimentally investigated by using a high-speed visual system. The visual experiments show that the bubble growth experiences a sphere-like growth stage and the asymmetric growth stage at the tip...

    We probe the nature of slow flow in the shear band of a 2D granular Couette experiment. The experiment consists of an inner shearing wheel, an outer circular boundary, and particles which occupy the space between these two. The mean flow is strictly azimuthal, maximal at the shearing wheel, and...

These flows propagate along frontal zones separating water masses that substantially differ in terms...
