Special Issue Information

Dear Colleagues,

Plasticity is an important property of metallic materials, as it determines the adaptability of metal during processing and the quality of the final product. Metal materials with high plasticity can be used to manufacture parts requiring complex shapes. At the same time, plasticity is closely related to other properties of metal, such as its strength, hardness, toughness, etc., and it is also an important index affecting the performance of metal materials. Good plasticity is usually accompanied by high levels of toughness, which prevent metal materials from fracturing under load. The main processing methods used to enhance the plasticity of metals include forging, stamping, drawing, extrusion and rolling. These processing methods are widely employed in automotive, aerospace, construction, electronics and other industries. The aim of this Special Issue is to publish original, valuable, and developed research papers that focus on plasticity and the plastic processing of metallic materials.

In this Special Issue, we welcome articles that present recentt research on plasticity and the plastic processing of metallic materials. The scope of this Special Issue includes, but is not limited to, the following topics: plastic property tests (such as tension, compression and torsion , etc); plasticity theory (such as constitutive equation, stress-strain, plastic springback, etc); metal material stamping, forging, extrusion, bending, or rolling processing; finite element simulation technology; the evolution of the microstructure; mechanical properties tests; and simulation during plastic processing.

This study investigates the longitudinal deformation behavior of ultra-high-strength steel (UHSS) during the cold rolling process. First, rolling experiments were conducted on UHSS, and longitudinal surface coordinates of the deformation zone were collected using a probe-type profiler to obtain the actual profile. The forward slip value was derived from production data. An elastic–plastic finite element model of the UHSS rolling process was then established using the nonlinear finite element method. The model calculated the contact arc shape and forward slip within the deformation zone, with errors of less than 15% for the contour and 10% for forward slip. The model was further used to analyze the impact of rolling parameters on contact profile, stress, and forward slip. The results indicate that reducing plate thickness and tension, along with increasing depression and yield strength, promotes the formation of a neutral zone in the deformation zone. The peak contact stress is linked to increased elastic compression of the rolls and the expansion of the roll exit. Additionally, increases in roll diameter, friction coefficient, and yield strength lead to a gradual increase in forward slip in the deformation zone. Full article
