Finite element analysis of gempita 8x8 underbelly deformation subjected to blast loading

Nowadays, armored personal carrier (APC) is largely used because of the revolution of war doctrine to carry the fighting element by vehicle, which means less infantry troops movement on foot. Malaysian Arm Forces has bought AV8 Gempita from Turkey and currently been deployed to carry out missions in...

Malaysian Arm Forces has bought AV8 Gempita from Turkey and currently been deployed to carry out missions in our country.
