Abstract The strain rate-dependent material characteristic of carbon fiber reinforced plastics (CFRP) is widely known and has been investigated in detail at coupon level. In this study, for the first time rate dependent a three-dimensional CFRP structure was investigated. evolution determined dependency correlated with results For purpose two special 3-point-bending fixtures were developed to o...

Abstract The work describes experiments and models related to auxetic (negative Poisson’s ratio) foams subjected low-frequency variable amplitude 3-point bending loading. A custom vibration test rig is designed used perform the dynamic of PU foam beams within range (1–20 Hz) 5 different displacement amplitudes. tested in this are manufactured using a simplified relatively low-cost uniaxially th...

A flexural model of four-point bending fatigue that has been experimentally validated for human cortical bone under load control was used to determine how load and displacement control testing affects the fatigue behavior of human cortical bone in three-point and symmetric four-point bending. Under load control, it was predicted that three-point bending produced no significant differences in fa...
