Damage Accumulation in Silica Glass Nanofibers [PDF]

Nano Letters, 2018
The origin of the brittle-to-ductile transition, experimentally observed in amorphous silica nanofibers as the sample size is reduced, is still debated. Here we investigate the issue by extensive molecular dynamics simulations at low and room temperatures for a broad range of sample sizes, with open and periodic boundary conditions.

Fatigue damage accumulation in CFRP [PDF]

WIT Transactions on The Built Environment, 2008
A cyclic bending study using a stress ratio of 0.1 was conducted on unidirectional 45CFRP with a 60% nominal fibre volume fraction. This allowed the continuous matrix damage evolution to be followed without the influence of delamination. Damage was monitored by changes in the fatigue modulus, increase in crack density and amount of permanent bending ...
