Presented is an experimental investigation of the machining characteristics and the effect of wire electrical discharge machine (WEDM) process parameters during machining of Al/ZrO2(p) particulate reinforced metal matrix composite (PRMMC). Experiments are carried out to investigate the effects of input parameters such as dielectric conductivity, pulse width, time between pulses, maximum feed rate, servo control mean reference voltage, short pulse time, wire feed rate, wire mechanical tension and dielectric injection pressure on performance measures like cutting velocity and surface roughness. Taguchi method based design of experiment and L36 (2138) mixed orthogonal array have been used for experimental investigation. Servo control mean reference voltage and wire feed rate have been identified as most significant and significant parameter for cutting velocity so called for material removal rate. Time between pulses and short pulse time have been identified as most significant and significant parameter for surface roughness height, Ra (µm). Optimum response characteristics estimated and identified the range of predicted confidence interval at 95% confidence level is 7.459 to 9.995 mm/min. for cutting velocity and 0.602 to 1.261 (µm) for surface roughness height Ra, respectively.

Results of experimental investigation of concrete and rocks under high rate loads of microsecond duration (2.5 µs) are presented. Tested samples are rectangular plates (150/150/15 mm) with a notch (70 mm long and 3 mm thick) containing a pre-crack (about 1 mm long). Dynamic loading was created utilizing electric wire explosion technique. An electric wire was placed between the faces of the notch at a distance of 20 mm from the tip of the pre-crack. After the wire explosion the trajectory of the extended crack and the fracture surface were studied. Measured dependence of the crack extension on the loading pulse energy gives the possibility of determining the threshold (minimal) amplitude of the load required to initiate fracture in the studied samples.
