Modelling Crack in Abaqus

Submitted by mahyar on

Hi everyone

I am new user in Abaqus, i read most of the posts related to the modelling the crack but unfortunately i didnt get a clear procedure, maybe it is due to my weakness in this software.

i want to model a crack in abaqus and analysis the crack propagation, actually i am working on piezoelectric material, but i want to know,  can you tell me different steps to model a crack and then how to analyze the propagation on it.

Please help me is this case.

Hands-On Microfluidics Simulation Workshop.

Submitted by Parameshwaran … on

The NNIN/C at the University of Michigan will be hosting a free Workshop
entitled ” Comsol Hands-on Workshop on Microfluidic Devices “.

In this Workshop, we will focus on COMSOL’s Microfluidics Module
which encompasses easy-to-use tools for the study of microfluidic
devices. Important applications include simulations of lab-on-a-chip
devices, digital microfluidics, electrokinetic and magnetokinetic
devices, inkjets, and micro-pumps.

The EU Emissions Trading Scheme and the UK Climate Change Act: a UK Perspective

Submitted by Kii Cajetan Barisi on

The European Union Emissions Trading Scheme (EU ETS), the largest emissions cap-and-trade scheme in the world, commenced on January 1, 2005. In addition, the United Kingdom's Climate Change Act 2008 has established the world's first legally binding emissions-reduction target, which requires at least an 80% reduction on 1990 emissions levels in the United Kingdom by 2050. The following article gives a brief overview of the EU ETS and of some of the steps being taken to reach the 80% reduction target under the Climate Change Act 2008.

Carbon Capture and Storage - Identified challenges to implementation

Submitted by Kii Cajetan Barisi on

Carbon capture and storage (CCS) is interesting as a case study of a CO2 mitigation technology that maintains considerable political and fiscal support even though its long-term economic viability is dependent on high carbon prices and even though its implementation will in many cases require that U.S. states and Canadian provinces enact new legislation and regulations. This article considers the current legislative debate in the U.S. and examines the ways in which the absence of federal climate change legislation in the U.S. and Canada affects both the price of carbon and the implementation of carbon abatement technologies. It also identifies regulatory gaps that must be addressed before CCS can be widely implemented.

SAFETY ISSUES IN BIOFUEL

Submitted by Kii Cajetan Barisi on

getting fuel from plants seems like a great proposition originally. It reduces dependence on foreign oil, and it doesn't produce the greenhouse gases that cause global warming â€" at least that's what advocates claim. But biofuels are not without their critics.

Some recent research suggests bio fuels could have a greater environmental impact â€" biodiversity loss, destruction of farmland, and the energy necessary to produce them, for example than burning fossil fuels, reports The Guardian, a British daily.
