Hence, the reaction of hard materials to shock loading is essential for alleviating shock-induced failures and damages.
Hence, the continuous impact of loading materials on the surface of the hammer tends to cause chemical-erosion [23].
Materials and Methods.
The microscopic procedures were carried out to determine the structure of the failed and as-received materials.

It was observed that PBS/NR composites are green-composites or eco-materials.
The development of biodegradable polymeric materials has been a subject of great research challenge in materials science.
Experimental part Materials.
These results show that PBS/NR composites are environmentally friendly and degradable materials that can be considered as alternatives to non-biodegradable plastic materials for applications.
