WitrynaThe results of analyses show that the value of absorbed energy by the longerons of new vehides exceeds the value of the oldest cars. The degradation of structures in the old cars has the significant influence on the absorbed energy. Keywords: vehicles impact; longerons crashworthiness; energy absorption; axial compression; buckling. 1. … WitrynaIn mechanics, an impact is a high force or shock applied over a short time period when two or more bodies collide.Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period. The effect depends critically on the relative velocity of the bodies to one another. At normal speeds, during a perfectly …
WitrynaPurpose: The foot-ground impact experienced during running produces a shock wave that is transmitted through the human skeletal system. This shock wave is attenuated … Witryna14 kwi 2024 · The plasticizing effect of glycerol in the MC/PC/K 3 PO 4 /glycerol system was confirmed by the change in the intensity of the samples’ FTIR absorption bands. The broadening of the XRD peaks demonstrates that the amorphous component of SBEs increases with increasing glycerol concentration, while EIS plots demonstrate an …
