They often face aggressive conditions such as mechanical vibration heat stress penetration of moisture or even abuse. These conditions favor the appearance of more or less serious defects ranging from a simple crack in the material. However To better predict their ruin it is important to understand the mechanical behavior of the materials and their damage mode depending on the type of load they undergo and either the generated default. The reliability of materials is an important concept to be regarded in estimating service life of materials. For this the present work aims to familiarize the mechanical behavior of different materials in our study we performed a comparison between the different specific energies .
