Non-proportional deformation paths for sheet metal: experiments and models [PDF]

, 2009
For mild steel, after significant plastic deformation in one direction, a subsequent deformation in an orthogonal direction shows a typical stress overshoot compared to monotonic deformation. This phenomenon is investigated experimentally and numerically

Scaling of the Strain Hardening Modulus of Glassy Polymers with the Flow Stress

, 2009
In a recent letter, Govaert et al. examined the relationship between strain hardening modulus $G_r$ and flow stress $\sigma_{flow}$ for five different glassy polymers.

Advanced constitutive modeling for application to sheet forming [PDF]

, 2018
Continuum constitutive descriptions of plasticity suitable for finite element simulations of sheet forming processes are succinctly discussed. Although multi-scale approaches allow for a more explicit representation of the physical deformation mechanisms

Study of Work-Hardening Rate Transient of AISI 409 Stainless Steel Under Strain Path Changes [PDF]

Materials Research
Metal forming processes present many changes in the strain path necessary to obtain the dimensions and shape of a metal part. The loading mode, the amount of prestrain, the initial state of a material and its respective substructural arrangements affect ...

Bauschinger effect in precipitation-strengthened aluminium alloy 2024

Materials Science and Engineering, 1987
Abstract The influence of precipitation strengthening on the Bauschinger effect of aluminium alloy 2024 has been investigated. The material was aged at 463 and 478 K for various lengths of time. Under certain aging and straining conditions, reverse flow curves with concave parts were observed.
