In this work the heat flux generated in a cutting process is simulated using the inverse heat conduction technique based on conjugate gradient method. A three-dimensional formulation is used both to describe the physical phenomenon and to solve the inverse problem. The machining process (turning) is simulated and instrumented with nine thermocouples at the(More)
This paper reports on a novel method for controlled release of huge amount of energy stored in a functionalized porous silicon (PS) on a silicon chip. This is achieved by adjusting the size and the separation distance between locally defined areas of PS. Such an approach allows multiple sequential or single explosions with defined energy outputs. The(More)
