DOI: 10.1016/j.engfracmech.2018.07.009
Abstract: Abstract Fissured rocks, widely existing in underground engineering structures, are quite sensitive to coupled static-dynamic loading conditions. Understanding the mechanical properties of fissured rocks under coupled loads is significant for the rational design and stability… read more here.

Abstract: Abstract A two dimensional (2D) mechanical-magneto-thermal model of direction-dependent magnetoelectric (ME) effect in Terfenol-D/PZT/Terfenol-D laminated composites is established. The expressions of ME coefficient at low and resonance frequencies are derived by the average field method,… read more here.
