A prediction model for the effective thermal conductivity of nanofluids considering agglomeration and the radial distribution function of nanoparticles
Conventional heat transfer fluids usually have low thermal conductivity, limiting their efficiency in many applications. Many experiments have shown that adding nanosize solid particles to conventional fluids ...

A theoretical study of steady-state wedge cutting through metal plates
The process of steady-state wedge cutting through steel plates is investigated by analyzing experimental data and develo** a simple and realistic model of the problem. Kinematics of the cutting process is di...

Ductile fracture in sheets under transverse strain gradients
The fully plastic fracture of a metal sheet subjected to a small transverse gradient of tensile strain near a reinforcement is modeled as mode I fracture under transverse plane strain (TPS). Necking and fractu...

Ductile fracture before localized necking in a strip under tension
Unexpected cracking with a 22° opening angle grew out of a rough-sheared edge before appreciable necking in an 0.79 by 37 mm mild steel strip, which normally fractures after diffuse and then localized oblique ...
