Investigation of deformation and collapse .

Traduire cette page

This paper demonstrates the quasi-static axial compression and high-speed axial compression tests of extruded magnesium alloy circular tubes for evaluating the crash and fracture behavior of mg parts. To capture the buckling and fracture behavior of Mg tube during the axial compression tests, FE simulation adopts different types of flow curves depending on the deformation mode such as tension ...

This mechanism is accompanied by a sudden significant drop in crushing force carrying capacity and found to be 26.2 kN in the 40° CFRP and 8.4 kN in the 35° KFRP tubes. The force-carrying capacity at the attained level for around 2 mm stroke in both corrugated tubes. Then after, the crushing force increases gradually to reach 65.7 kN at 27.3 mm and 30.7 kN at 24.9 mm in the 40° CFRP and 35 ...

01/06/2020 · Investigation of the crushing behaviors of density-graded RHCS structures with continuously varying in density reveals that the deformation modes and crushing response are sensitive to the impact velocity as well as the density distribution properties. Under low-velocity impact, the shear bands occur from the low density end then spread to the high density end. At moderate impact .
