Longitudinal Compressive Property of Three-Dimensional Four-Step Braided Composites after Cyclic Hygrothermal Aging under High Strain Rates

Applied Sciences, 2020
The longitudinal compressive behavior of the three-dimensional four-step braided composites after cyclic hygrothermal aging was investigated using a split Hopkinson pressure bar (SHPB) apparatus under high strain rates (1100~1250 s−1, 1400~1600 s ...

Mechanisms of types B and C serrations in the tensile flow curve of C-bearing high Mn steel

Journal of Materials Research and Technology, 2023
In the present study, the mechanisms of types B and C serrations in the tensile curves of C-bearing high Mn steel were investigated. Many tensile tests were performed at various temperatures (313–573 K) with two different initial strain rates (ε˙ini = 1 ×

Conditions for development dynamic strain steel ageing

Science and Transport Progress, 2011
Contrary to the one-sided straining, after compressive predeformation with subsequent tension the shift of appearing the first stress stall to higher values of strains can be observed. The values of compressive predeformation and the strain of first stress stall appearance are approximately equal.
