The use of piezoceramic materials with resistive shunting circuits has previously been shown to increase passive structural vibration damping. The ability to tailor the frequency dependence of damping is especially attractive when active linear time-invariant control of uncertain structures is to be

The dynamics of the normal zone initiated by a local heat pulse in a superconductor carrying a transport current is studied theoretically. An approximate method is considered, from which analytical formulae are obtained for the minimum heat pulse energy EC required to destroy the superconductivity.
## A finite element based crack-closure integral for determining strain energy release rates for two-dimensional elastostatic and elastodynamic crack problems in finite bodies is evaluated. Both the J-integral and crack-closure integral are used to obtain strain energy release rates from the finit
