Crack Closure and Shape Restoration Using NiTi Shape-Memory Alloy
Crack Closure Shape Memory Alloy Actuator Shape Recovery Shape Restoration Structure Repair
2011/11/22
Because of the high actuation stress and high recovery strain, NiTi shape-memory alloy (SMA) has been proposed for shape/position control and crack closure in structures for many years. In this paper,...
A new theoretical paradigm to describe hysteresis,discrete memory and nonlinear elastic wave propagation in rock
new theoretical paradigm hysteresis discrete memory nonlinear elastic wave propagation
2009/11/16
The velocity of sound in rock is a strong function of pressure, indicating that wave propagation in rocks is very nonlinear. The quasistatic elastic properties of rocks axe hysteretic, possessing disc...
