Are cancer cells able to metastasize without degrading extracellular matrix?

Hello all, It is clear that cancer cells need to migrate within host tissue during metastasis, but they face the extracellular matrix as a physical barrier. Is it necessary for them to degrade...

Joint behaviour in Abaqus is not captured well?

I am working on roof joint and trying to simulate the behaviour in Abaqus. I am successful in running the model but the final graph does not follow the experimental curve in the negative direction...

How to find the right number of integration points in second order 3d finite elements?

I am familiar with finite element simulations and numerical schemes like the Gauss Legendre quadrature. I also know that the Gauss integration yields exact values for polynomials up to degree 2n-1...

What could be the reason for not having further low chi square value (better agreement) in my refinement result?

I have tried every combination of parameter changes and after that i have a poor chi square value. I can't get it lower any further. I know there have been a lot of discussion about Rietveld...
