Bending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition

The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

Fracture mechanics analysis of thin coatings under plane-strain indentation

A combined experimental/analytical work is carried out to elucidate the fracture resistance of a thin, hard coating bonded to a semi-infinite substrate due to indentation by a cylindrical surface. The bending of the coating under the softer substrate induces concentrated tensile stress regions at the lower and upper surfaces of the coating, from which cracks may ensue. The evolution of such dam...

The Fundamental Differences between Iranian Traditional Medicine and Popular Medicine

The complete system of Iranian traditional medicine, which is distinct from conventional medicine, is one of the significant systems of traditional medicine that developed at the birthplace of human civilizations. This article presents a logical and philosophical analysis of the distinctions between Iranian traditional medicine and conventional medicine. In this analytical-descriptive review s...

Cracking sheets: oscillatory fracture paths in thin elastic sheets.

When a blunt cutting tool is forced through a thin elastic sheet that is held along its lateral boundaries, a strikingly regular wavy cut can be left behind, examples of which are presented in Fig. 1. The thin film is brittle, hence it undergoes negligible irreversible deformation besides fracture. For tools much wider than the film’s thickness, the crack tip follows a highly reproducible nonsi...
