Difference between deformation and strain
WebSep 12, 2024 · Figure 12.6. 1: Typical stress-strain plot for a metal under a load: The graph ends at the fracture point. The arrows show the direction of changes under an ever-increasing load. Points H and E are the linearity and elasticity limits, respectively. Between points H and E, the behavior is nonlinear. WebMay 30, 2024 · From the strain data (Figure 6 (b and d)), dominant plastic deformation/strain hardening for all materials were found from the first peak of the strain vs. time curve. The magnitude of strain was also higher than slipping case. Furthermore, the strain increased for higher RPM and feed rate (Figure 6 (d)). However both positive …
