Discrete Element Modeling of Permanent Deformation Accumulation in Railroad Ballast Considering Particle Breakage

open access: yesFrontiers in Built Environment, 2020
Particle shape and mineralogy have been found to greatly affect railroad ballast response under train loading. In this research effort, the effect of particle breakage on ballast permanent deformation behavior was studied using the Discrete Element ...

Beam-Induced Damage Mechanisms and their Calculation [PDF]

open access: yes, 2016
The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If the beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes of material ...

Macro-mechanical and microscopic study of the fatigue damage behaviour of a carbon fabric/PPS thermoplastic composite [PDF]

open access: yes, 2011
This manuscript elaborates on the tension-tension fatigue behaviour of a carbon fabric reinforced polyphenylene sulphide. The damage behaviour will be investigated by (i) conducting fatigue experiments, in order to determine the macroscopic behaviour ...
