Material property identification typically involves static or quasi-static testing methods, such as compression, tension, bending, torsion, shearing, and punching under varying velocities. These methods have been extensively studied, standardized, and documented. However, the behavior of materials changes significantly when subjected to loading at velocities exceeding the Mach number. At such high deformation rates, dissipative forces become a critical factor due to their influence on the material's response. This study focuses on developing a methodology to determine the dissipative-elastic properties of materials using a rheological model. The proposed approach assumes that the constitutive behavior of the material, particularly in the range of permanent (destructive) deformations, can be described by this rheological model. The dissipative characteristics of the material are defined by the parameters k, h, and a velocity-dependent function g(v), which can take any form. This framework enables the detailed evaluation of material behavior under conditions involving high strain rates and significant dissipative forces, providing a robust foundation for understanding and modeling such dynamic interactions.

摘要

Material property identification typically involves static or quasi-static testing methods, such as compression, tension, bending, torsion, shearing, and punching under varying velocities. These methods have been extensively studied, standardized, and documented. However, the behavior of materials changes significantly when subjected to loading at velocities exceeding the Mach number. At such high deformation rates, dissipative forces become a critical factor due to their influence on the material's response. This study focuses on developing a methodology to determine the dissipative-elastic properties of materials using a rheological model. The proposed approach assumes that the constitutive behavior of the material, particularly in the range of permanent (destructive) deformations, can be described by this rheological model. The dissipative characteristics of the material are defined by the parameters k, h, and a velocity-dependent function g(v), which can take any form. This framework enables the detailed evaluation of material behavior under conditions involving high strain rates and significant dissipative forces, providing a robust foundation for understanding and modeling such dynamic interactions.
