#Fracture glass fractureme crack#

These impact loads could vary from small stone pellets to bullets, resulting in a minor crack to a catastrophic failure of the glass structure, respectively ( Bobaru et al., 2012 Hu et al., 2013). One of the major causes of failure in glass is the sudden load, such as impact, to which they are exposed to during the service period. Glass, an archetypical brittle material, is ubiquitously used in everyday life from car wind shields to smart phone screens ( Mauro, 2014 Mauro and Zanotto, 2014 Mauro et al., 2014 Wang M. This improved understanding can pave way to the design and development of glasses with improved impact-resistance for applications ranging from windshields and smart-phone screens to ballistics. Overall, the present study illustrates how peridynamic simulations can offer new insights into the fracture mechanics of glasses subjected to ballistic impacts. Through an auto-regressive analysis of the evolution of cracks, we demonstrate that the self-affine growth of cracks leads to this power-law dependence. Interestingly, we observe a power-law dependence between the total damage and the fracture energy of the glass plate. In particular, we analyze the role of bullet velocity, bullet material, and elastic modulus, fracture energy, and radius of the plate. Here, using peridynamics simulations, we investigate the role of the mechanical properties and geometry in determining the overall damage on a glass plate subjected to ballistic impact. While in situ experimental studies on impact-induced damage are challenging due to the short timescales involved, continuum-based computational studies are complicated by the discontinuity in the displacement field arising from the propagation of cracks. Most glasses are often exposed to impact loading during their service life, which may lead to the failure of the structure.
