Plasmas and MHD Shocks

1. Introduction In the jargon of hydrodynamic transport phenomena, a ‘shock’ is a discontinuity separating two different regions in an otherwise continuous medium (Kallenrode, 2004). It is associated with a disturbance moving faster than the rate of signal propagation in the environment, such as an airplane traveling at a speed greater than the speed of […]

Plasticity: Tresca and von Mises Yield Criteria

1. Yield Surfaces Plasticity theory is the study of structural strains beyond the linear region in which deformations are elastic and Hooke’s law describes mechanical behavior. The existence of a fixed region of admissible generalized stresses is a key concept in this field. When modelling elastic-plastic behavior, it is assumed that at all times, the […]
