ME 354 LAB #4: DISCUSSION OF THE TORSION TEST
σ= 3 τ~ xy.... during the torsion test the effective stress (σ) equaled the true shear stress (τ~ xy) multiplied by a constant factor ( 3) What was the effective strain during the torsion test? The only strain induced during the torsion test was the true shear strain γxy ~ . No other strains were present: 0~ = ~ = ~ = ~ = ~ =
