This study presents a framework for plasticity and elastoplastic damage mechanics by treating materials as reactive solids whose internal composition evolves in response to applied loading. Using the framework of constrained reactive mixtur...
Roles of texture and latent hardening on plastic anisotropy of face-centered-cubic materials during multi-axial loading [0.03%]
多轴载荷下fcc材料塑性各向异性中织构和隐式硬化的作用
M S Pham,A Creuziger,M Iadicola et al.
M S Pham et al.
This study investigates the joint impact of preferred texture and latent hardening on the plastic anisotropy of face centered cubic (FCC) materials. The main result is that both aspects have significant impact on the anisotropy, but the two...
Characterizing viscoelastic materials via ensemble-based data assimilation of bubble collapse observations [0.03%]
基于数据同化的气泡溃灭观测表征粘弹性材料属性

Jean-Sebastien Spratt et al.
Viscoelastic material properties at high strain rates are needed to model many biological and medical systems. Bubble cavitation can induce such strain rates, and the resulting bubble dynamics are sensitive to the material properties. Thus,...
The Geometry of Incompatibility in Growing Soft Tissues: Theory and Numerical Characterization [0.03%]
生长软组织不相容性的几何理论及数值特征化
Taeksang Lee,Maria A Holland,Johannes Weickenmeier et al.
Taeksang Lee et al.
Tissues in vivo are not stress-free. As we grow, our tissues adapt to different physiological and disease conditions through growth and remodeling. This adaptation occurs at the microscopic scale, where cells control the microstructure of t...
Effect of receptors on the resonant and transient harmonic vibrations of Coronavirus [0.03%]
