Due to surface tension, a beading instability takes place in long enough fluid column that results the breakup of and formation smaller packets with same overall volume but area. Similarly, soft elastic cylinder under axial stretching can develop an if tension is large enough. This occurs when force reaches maximum fixed or force. However, unlike situation fluids where develops finite wavelengt...

Adding fibers to a liquid thread increases the viscosity, hence slows early stretching of thread, but it also alters later breakup dynamics and induces considerable variability in necking shapes.

A unified experimental-computational study on ductile fracture initiation and propagation during small punch testing is presented. Tests are carried out at room temperature with unnotched disks of different thicknesses where large-scale yielding prevails. In thinner specimens, the fracture occurs with severe necking under membrane tension, whereas for thicker ones a through thickness shearing m...
