“…Recently, a thermodynamically consistent constitutive model based on rate-dependent CP was developed to predict the stress, temperature and retained austenite evolution responses of a QP3Mn alloy over a wide range of strain rates and temperatures [ 232 ], where plastic slip and transformation kinetics laws were proposed to account for the temperature, strain and orientation-dependent mechanical behavior. Nowadays, the application of CP models in predicting the constitutive behaviors of lightweight alloys under complex loading conditions has drawn significant attention [ 233 , 234 , 235 , 236 , 237 ]. As shown in Figure 15 , Bong et al [ 238 ] proposed a CP approach based on a three-component dislocation density model as a virtual experimental model to accurately predict the non-proportional anisotropic hardening behavior of ultra-thin sheet metals.…”

Lightweight sheet metals are attractive for aerospace and automotive applications due to their exceptional properties, such as low density and high strength. Sheet metal forming (SMF) is a key technology to manufacturing lightweight thin-walled complex-shaped components. With the development of SMF, numerical simulation and theoretical modelling are promoted to enhance the performance of new SMF technologies. Thus, it is extraordinarily valuable to present a comprehensive review of historical development in SMF followed by state-of-the-art advanced characterization and modelling approaches for lightweight metallic materials. First, the importance of lightweight materials and their relationship with SMF followed by the historical development of SMF are reviewed. Then, the progress of advanced finite element technologies for simulating metal forming with lightweight alloys is covered. The constitutive modelling of lightweight alloys with an explanation of state-of-the-art advanced characterization to identify the constitutive parameters are presented. Then, the formability of sheet metals with major influencing factors, the techniques for measuring surface strains in SMF and the experimental and modelling approaches for determining the formability limits are clarified. Finally, the review is concluded by affording discussion of the present and future trends which may be used in SMF for lightweight metallic materials.
