hi 

i am sajib,I am very very new ABAQUS user.



i am modeling RCC simply supported BEAM STRENGTHEN IN FLEXURE WITH FRP using ABAQUS.

I HAVE USED S4R FOR FRP, 

C3D8R FOR SOLID AND T3D2 AS STEEL 

cracked conrete model used,elastic plastic model for steel n elastic model for frp

I have used correct E values. 

Hi

can Anyone help me to find johnson-cook failure model damage parameters(d1, d2, d3, d4) for Advanced hgih strength steels like DP and TRIP?

thanks

Hi, thanks for your attention!!!

I have recently read the book, Introduction to Micromechanics and Nanmechanics, written by ShaoFan, Li. This is
really a good book for the freshmen who are interested in
micromechanics area. 

But one problem puzzled me for along time,  the puzzlement i have put it in the attached file.

If you know the answer,please tell me. You kindly reply will be great appreciated! Thank you very much!!!

Hi friends,

I would like to calculate stress intensity factor for bimaterial interface using finite element method. Do you have any suggestion about it? Actually I know a method. According to this method,

1-obtain crack face displacement using numerical solution

2- use dundur parameter 

Is this method is correct/enough?

As you know Franc2D code calcuate SIF for mode I and mode I. But I do not know this code can calculate SIF for bimaterial interface? 

Thanks
