In this paper, the linear transformation method (LTM) to control flexural waves propagating in thin plates is presented. Unlike earlier studies, only a small number of homogeneous materials with no requirement of in-plane forces or pre-stress are needed, which tremendously simplifies the implementation of devices for flexural waves. An invisibility cloak(More)
An interior ballistic simulation of the canister launched missiles has been developed with the help of FLUENT. One of the special features of this simulation is the almost uniform acceleration which occurs 0.25s after startup and keeps the missile shockless during ejection. The calculation was done efficiently in FLUENT after setting all the required(More)
