Effect of Wear on the Evolution of Contact Pressure at a Bimaterial Sliding Interface

Submitted by Antonio Papangelo on

The eigenfunction method pioneered by Galin (J Appl Math Mech 40: 981–986, 1976) is extended to provide a general solution to the transient evolution of contact pressure and wear of two sliding elastic half-planes, under the assumption that there is full contact and that the Archard–Reye wear law applies. The governing equations are first developed for sinusoidal profiles with exponential growth rates. The contact condition and the wear law lead to a characteristic equation for the growth rate and more general solutions are developed by superposition.

Computer Graphics Algorithms and Image-Based Multiscale Multigrid Framework

Submitted by karelmatous on

We present a novel image-based multiscale multigrid solver that can efficiently address the computational complexity associated with highly heterogeneous systems. This solver is developed based on an image-based, multiresolution model that enables reliable data flow between corresponding computational grids and provides large data compression. A set of inter-grid operators is constructed based on the microstructural data which remedies the issue of missing coarse grid information.

On the suitability of slow strain rate tensile testing for assessing hydrogen embrittlement susceptibility

Submitted by Emilio Martíne… on

I hope that some of you will find this work interesting. We show that early cracking occurs in slow strain rate tensile testing (SSRT), which compromises the capabilities of this popular experiment for measuring hydrogen embrittlement susceptibility.

Wallner lines, crack velocity and mechanisms of fracture in a brittle bulk metallic glass

Submitted by Parag Tandaiya on

A few years ago, we observed Wallner Lines on the fracture surface of a brittle Bulk Metallic Glass and explained the process of formation of nanocorrugations on the fracture surface.

We published our research in Acta Materialia in the paper: 'Wallner lines, crack velocity and mechanisms of fracture in a brittle bulk metallic glass'.

I hope the experimental fracture mechanicians would particularly enjoy reading this paper and find it useful in their research.

On the mechanism and the length scales involved in the ductile fracture of a bulk metallic glass

Submitted by Parag Tandaiya on

A few years ago we published a paper in Acta Materialia elucidating the mechanism and length scales in the ductile fracture of bulk metallic glass through experiments and finite element simulations.

The link to the paper is here: 'On the mechanism and the length scales involved in the ductile fracture of a bulk metallic glass'.

I hope you enjoy reading the paper and find it useful in your research.
