Metal Plasticity: Experimental Characterization and Constitutive Modeling outlines the fundamentals of plastic deformation of metals, related constitutive modeling techniques, and how best to apply these modeling techniques. The book summarizes the plastic behaviors of metals based on experimental observations while also reviewing related constitutive models used to determine their plastic deformation, including isotropic yield functions, anisotropic yield functions, asymmetric yield functions, anisotropic hardening yield functions, and more. It demonstrates the yield surfaces of functions under 2D plane stress, 3D plane stress with shear stress effect, and 3D triaxial loading, amongst others.
The development of different plasticity models, including their form, parameters, calibration, accuracy, advantages, and disadvantages are outlined as well, and the book also summarizes and compares various models, emphasizing their costs and user-friendliness, thus allowing readers to select the model that best meets their needs.

Dr. Yanshan Lou is a professor at the School of Mechanical Engineering, Xi’an Jiaotong University, China. He earned his PhD from KAIST in 2012, worked in Australia and TU Dortmund (as an Alexander von Humboldt scholar), and joined Xi’an Jiaotong University in 2018. He received the O.C. Zienkiewicz Award in 2019 and the International Journal of Plasticity Young Researcher Award in 2020. His anisotropic yield function and ductile fracture criteria were implemented into Ansys LS-DYNA as *MAT_263 or *MAT_Lou-Yoon_Anisotropic_Plasticity. His research focuses on anisotropic/asymmetric yielding behaviors, large-strain hardening, ductile fracture, strain rate hardening, thermal softening, artificial neural networks (ANNs), lightweight design, crash and impact analysis.
