RISAn Eccentric Ellipse Failure Criterion for Amorphous Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We proposed an eccentric ellipse criterion to describe the failure of amorphous materials under a combination of normal stress σ and shear stress τ. This criterion can reflect a tension–compression strength asymmetry, and ...
Scaling Effect of Dry Adhesion for Microfibrils and Transition Size to Flaw Insensitivity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanics of detachment (e.g., a cylindrical fibril separating from a dissimilar substrate) has been treated in the perspectives of contact mechanics and fracture mechanics theory along with numerical simulations, but ...
Study on the Influential Factors in and the Optimization of Asphalt Mixture Scanning with X-Ray CT Technology
Publisher: American Society of Civil Engineers
Abstract: The effects of sample size, aggregate lithology, and compaction pattern on image scanning quality were determined using 225 kV industrial computer tomography equipment. Moreover, the scanning parameters of common Marshall ...
Study on the Microstructure Evolution and Mechanical Properties of Cu/Cu41Sn11/Cu Solder Joint During High-Temperature Aging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper focused on the changes in microstructure and mechanical properties of the full Cu41Sn11 solder joint (Cu/Cu41Sn11/Cu) during isothermal aging at 420 °C. It was motivated by potential applications of Cu–Sn ...
