Engine control unit consists of many electronic components like capacitors, inductor coils, Ball Grid Array (BGA) and Ceramic chips which are prone to fail during drop. As per ISO 16750-3 standard electronic components are dropped from one meter height on rigid wall in six different dimensional axis to check the reliability of the system [4]. Unless the ECU mechanical structure fails or components...
This work demonstrates a methodology to analyze small time deformations in conico-cylindrical, multi-material projectile containing explosive material during sub-ordnance velocity impact with the semi-infinite target as hard soil. A 3-Dimensional computational model is developed and analysed using explicit analysis in ANSYS AUTODYN Hydrocode for the Lagrangian domain. The problem was studied for two...
