✦ Synopsis
After summarizing simple models of (a) internal friction and (b) crack propagation, in which essential input is a dissipative force which is a constant times velocity _ u, where u is the displacement, their consequences are brought into contact with processes (a) and (b) when it is known from experiment that phonon emission constitutes a major damping mechanism. Same experiments on both (a) and (b) are noted, where such radiation force is important. One must expect then that it becomes essential to transcend damping which
