matrix

Read Dr Marcin Kaminski's (Technical University
of Lodz) September 2011 Editorial for ICE-journal Engineering and Computational Mechanics for free here.

If I have the matrix A=[1 2 3;4 5 6;7 8 9] and the matrix B={1;2;3}

of course A*B is C={14;32;50}.

My question how can I get the matrix A if I have B and C ?

thank in advance

Hi,

I am simulating failure of concrete in tension and compression on a concrete representative element volume. I have modeled mortar matrix and aggregate (inclusion) separately i.e my model consists of two material and assumed them as perfectly bonded. My question is, if I add interface zone between matrix and inclusion how will it effect my overall failre or can I neglect inerface.

With Warm Regards
