Impact Depth on Glass Surface Caused by Sand Particles

Abstract

Brittle materials in general and particularly glass are very sensitive to dynamic particles impacts of different nature. The ancient objects in glass (building, monuments) and some precious objects are subjected to atmospheric aggressions such as humidity, sand particles, hail,…etc.). Their surfaces are however, often exposed to severe climatic conditions in an environment where the sand wind is a daily phenomenon or beach wind. Many degradation processes due to erosion affect significantly surfaces of buildings that are part of the Cultural Heritage.
