Web2 days ago · The T-C asymmetry is closely correlated to the asymmetry in the critical resolved shear stress (CRSS) of active deformation modes (e.g., dislocation slip and twinning) between tension and compression. In our study, no twins were captured in the current MEA under either dynamic tension or compression even at very high strain rates. Web11 Apr 2024 · In IF-1200 K test, in the tension half-cycle, the σ max t still lies between the stresses under TMF loadings, while in the compression half-cycle, the σ max c is larger than that under TMF loadings, and this is caused by the tension-compression asymmetry of the sample under TMF loadings. marelli motori south africa
