my project is to compare the experimental work on brick masonry with numerical work in abaqus software by applying mohr-coulomb model. as in abaqus software we need different parameters to put, but in experimental work I could not found all these parameters (modulus of elasticity, poisson ratio, friction angle, dilation angle, cohesion yield stress, Abs plastic strain, tension cutoff stress, tensile plastic strain etc). so how to find these parameters? any equations or any other way of finding these parameters.
THANKS
Dear Suleman,
In this cases you should find the properties of specific soil in natural media and find your parameters or use refrence articles that did the above step and find the parameter. Another solution is to use the Abaqus examples and benchmarks soil properties. If none of above is available, you ought to go to site and take the sample and find your parameters in the lab.
Good luck
The soil parameters need to find out by conducting triaxial test with drainage conditions also to be considered in tests. The Young's modulus of soil to be find out from stress - strain curve obtained from triaxial test. Cohesion and angle of internal friction can be obtained from Mohr circles drawn from the test. The soil parameters can also be obtained from general correlations are available from literature. I suggest you to read the book for soil parameters..The book titled 'Foundation analysis and design' by J.E. Bowles. also i suggest you to read ABAQUS manual or the papers published by based on the abaqus work..
There are correlations based on experimental tests, you can correlate you compression test results using following proposed correlations, and then can calculate paramters to model Mohr Column failure criterion in ABAQUS, Refer to following paper,
"Experimental Investigation on The Characterization of Solid Clay Brick Masonry for Lateral Shear Strength Evaluation"
thanks for everyone for your valueable information and specially for Sadiq shamsher of UET Peshawar
Hello Sadiq Shamsher
I cannot access your .doc file. Can you kindly provide a pdf of it?
Thanks Sadiq Shamsher
I have been able to access the pdf. But there is no way of referencing this article. It contains no publication details namely Journal of publication; date of publication; page numbers. Could please provide these details? Thank you.
