PE-HD fatigue damage accumulation under variable loading based on various damage models
eXPRESS Polymer Letters, 2017 Despite numerous studies on fatigue of polymer materials under variable loading, there is little work on highdensity polyethylene (PE-HD). In this context, an experimental analysis for determining the fatigue strength of PE-100, under constant and ...

Damage accumulation of bovine bone under variable amplitude loads
Bone Reports, 2016 Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study on damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear damage accumulation hypothesis, is predictive of fatigue failure in bone.

Modelling of dynamic damage and failure in aluminium alloys [PDF]
, 2012 A physically based damage and failure model, applicable to orthotropic metals is proposed in this paper. To account for the physical mechanisms of failure, the concept of thermally activated damage initially proposed by Klepaczko [1], has been adopted as

INTERPRETING ENVIRONAMENTAL VARIABILITY FROM DAMAGE SENSITIVE FEATURES
10th ECCOMAS Thematic Conference on Smart Structures and Materials, 2023 Mitigation of Environmental and Operational Variabilities (EOVs) remains oneof the main challenges to adopt Structural Health Monitoring (SHM) technologies. Its implementation in wind turbines is one of the most challenging due to the adverse weather and operating conditions these structures have to face.
