Numerical study of the temperature and porosity effects on the fracture propagation in a 2D network of elastic bonds [PDF]

, 2005
This article reports results concerning the fracture of a 2d triangular lattice of atoms linked by springs. The lattice is submitted to controlled strain tests and the influence of both porosity and temperature on failure is investigated. The porosity is

MORPHOLOGICAL OBSERVATIONS OF FRACTURE OF POLYSTYRENES

Sen'i Gakkaishi, 1973
General mode of deformation and the morphology of fracture surface in polymers have been studied systematically from the point of view of fluidity of molecular chains.Particularly for polystyrene, the mechanism of the propagation of fracture has been investigated in the light of morphology observed by the scanning type electron microscope.Materials may

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.

A fabrication history based strain-fatigue model for prediction of crack initiation in a radial loading wheel [PDF]

, 2017
A strain-based fatigue model concerning fabrication history is applied to predict the fatigue life of a commercial car wheel under radial loads. As the prior conditions, the strain fatigue testing is performed on standard specimen of DP590 and FB540 ...

Unusual Morphology of a Distal Femur Fracture

Cureus
Fractures of the distal femur are rare but serious injuries that often follow a distinct pattern, occurring more frequently in both younger and older populations. In younger individuals, these fractures usually result from high-energy trauma, while in the elderly, they are often caused by domestic accidents.
