Glass thermal stress and fracture

Submitted by pinew on

I have an investigation on glass fracture in fire.

I have a fortran program and it can calculate the thermal stress with steady-state temperature and force load using finite element method, Now I want to change it to transient temperature and force load.

I wonder which method should be taken? I'd like to calculate the fracture at last.

Please help me! 

Thank you very much.

Predictive modeling schemes for wear in tribometers

Study of wear in complex micro-mechanical components is often accomplished experimentally using a pin-

on-disc and twin-disc tribometer. The present paper proposes an approach that involves a computationally

efficient incremental implementation of Archard’s wear model on the global scale for modeling sliding and

slipping wear in such experiments. It will be shown that this fast simplistic numerical tool can be used to

identify the wear coefficient from pin-on-disc experimental data and also predict the wear depths within a

DEAL.ii

Submitted by Roozbeh Sanaei on

deal.II is a C++ program library targeted at adaptive
finite elements and error estimation. It uses state-of-the-art programming
techniques of the C++ programming language to offer you a modern interface to
the complex data structures and algorithms required for adaptivity and enables
you to use a variety of finite elements in one, two, and three space dimensions,
as well as time-dependent problems.

ALBERTA

ALBERTA is an
Adaptive multiLevel finite element toolbox using
Bisectioning refinement and Error control by Residual
Techniques for scientific Applications. Its design is based on
appropriate data structures holding geometrical, finite element, and algebraic
information. Using such data structures, abstract adaptive methods for
stationary and time dependent problems, assembly tools for discrete systems, and
dimension dependent tasks like mesh modifications can be provided in a library.
This allows dimension-independent development and programming of a general class
