Abaqus - cohesive concrete and epoxy

Submitted by parthathawale on Fri, 09/30/2011 - 00:19

Hi,

I was browsing through this forum which I find very helpful.

I am trying to model a simple shear pull out test by simulating debonding in abaqus.

epoxy is bonded between concrete and frp.

i am pulling frp from one end by applying a load while other end of concrete is fixed.

epoxy is modeled as cohesive with quad damage and traction

interaction has been defined as hard contact, cohesive and damage (initiation, evolution and stabilization).

automatic stabilization is also provided by inputing the damping factor.

a question about Euler beam in ABAQUS

Submitted by chunhuizhang on Thu, 09/29/2011 - 05:12

software

To eliminate the unwanted axial strain constraint, in Abaqus the stretch dL/dS at the node of each such element is taken as an internal variable, local to the element (a third internal node is created for this purpose, and so it is not shared with neighboring elements.)

Above paragraph is excerpted from chapter about Euler beam theory in ABAQUS theory manual.

Post-Doctoral Positions at the Tsinghua Center for Combustion Energy

Submitted by frankwanger on Thu, 09/29/2011 - 03:18

job

A Center for Combustion Energy has been established at Tsinghua University in Beijing, China.

The need for such a center is motivated by the central role that combustion plays in energy sustainability and climate change,

by the emergence of China as a major industrialized nation and her commitment to seek solutions to these global problems,

and by the potential that combustion can contribute to the advance of diverse disciplines of frontier science that involve reacting flows.

ExpRing-----a tool to simulate fragment of brittle materials

Submitted by Duan Zhong on Thu, 09/29/2011 - 01:37

software

This is a free tool to simulate the fragment of brittle materials. You can use it to calculate the fragmentation of some differernt materials with different weakened styles. Also you can use different model to analyze your fragment process. The tool and its introduction are showing the attachment.
