Abstract: Discrete dislocation dynamics is a numerical tool developed to model the plasticity of crystalline materials at an intermediate length scale, between the atomistic modeling and the crystal ...

Abstract: An analytical solution for the extended stress field of the fundamental problem of interfacial Somigliana ring dislocation in fiber-matrix composites is obtained. The result of this work provides ...

Abstract: A thermodynamical theory of elastoplasticity including kinematic hardening and dislocation density tensor is developed. The theory is self-consistent and is based on two fundamental principles of ...

Abstract: Multilayer thin films of CuNb, CuNi, and CuNbNi with 20 nm individual layer thicknesses were fabricated by magnetron sputtering on oxide coated silicon wafers. The mechanical properties of the ...

Abstract: The instability of biaxial stretching of thin sheets of viscoplastic metals under plane stress conditions is investigated using a linear stability analysis. An instability criterion for biaxial ...
