Adiabatic shear-Dynamic recrystallization-Softening

The attached results address the extent to which the presence of a nanograined, dynamically recrystallized phase may soften a material (in that case Ti6Al4V), causing ultimately failure by shear localization.

Comments welcome.

free public repositories of papers and books

I have been told that it is no longer needed to search for papers on regular libraries and libraries' services, as there is this web site which contains much more than even the best "legal" library www.sci-hub.cc

Society of Engineering Science (SES) Board of Directors---Call for Nominations

On behalf of the Board of Directors of SES, we are soliciting nominations to fill 2 positions in the SES Board of Directors. The SES members will elect the directors from the nominees. The Board plays an important role in defining the vision of SES, organizing various SES events, managing society finances, and evaluating nominations for the SES awards. Please nominate your colleagues to serve the Board. All we need are the name of the nominee and 1-2 sentences on why you think he/she might be appropriate for the SES Board.

A simplified model for railway catenary wire dynamics

In this paper, a simplified analytic model for the dynamic behaviour of railway catenary wire is presented. The model is discussed and validated with the help of numerical results obtained by a finite element code, for the case of a typical Italian railway installation. The simplified model is convenient from the computational point of view and is useful for sensitivity analysis. Some parametric studies have been developed by considering as free parameters the velocity and the distance of the train pantographs and looking at their effect on catenary dynamics.

Google Maps/Earth Computer Graphics Algorithms for Model Reduction in Mechanics of Materials

We present an innovative image-based modeling technique, based on Google Earth like algorithms, to effectively resolve intricate material morphology and address the computational complexity associated with heterogeneous materials. This sharp volumetric billboard algorithm stems from a volumetric billboard method, a multi-resolution modeling strategy in computer graphics. In this work, we enhance volumetric billboards through a sharpening filter to reconstruct the statistical information of heterogeneous systems.

Arc Length Continuation method fails at low arc length values.

I have implemented a Arc length continuation method for material non-linearity. The program quits with low arc length values while it progresses well for high arc length values. I am attaching a png image for your understating  about the nature of the force deformation curve. Can you please clarify me about the problem and provide me any suggestions on it.

Thanks in advance.

Any helpful information about 2 & 3 surface models

Does anyone have any helpful information (Organised governing equations & subroutine files) about Two & Three surface models which are developed by Shen & Goto respectively?
