Nonlinear vibrations Perturbation methods Period–amplitude relation
2015/8/27
In this work we propose a class of problems in nonlinear vibrations related to avoiding undesirable hysteresis and jump phenomena and offer sample conservative systems for which the backbone curve is ...
Regional plantar foot pressure distributions on high-heeled shoes-shank curve effects
High-heeled shoes Shank curve Plantar arch height Plantar pressure Foot biomechanics
2012/2/28
Forefoot pain is common in high-heeled shoe wearers due to the high pressure caused by the center of body mass moving forward and the increased arch height with heel elevation. Sufficient arch support...
Evaluation of load control end-feed in hydroforming of pre-bent dp600 steel tube using the extended stress-based forming limit curve (xsflc) failure criterion
