Hello Manuel Benoit Ildefonse from Montpellier-France has worked experimentally on the subject you refer to. Check in his papers Cheers Guido >Hi everyone, I'm searching for works that deal with rotation of rigid >particles by combination of simple and pure shear in a similar way as in >the Ghosh and Ramberg (1976) paper on rotation of inclusion under such >conditions. I'd like to know as well your opinion about using this >rotations to estimate the simple shear/pure shear ratio in a shear zone >and if there are other methods to calculate this ratio. > >Thanks a lot, > >Manuel > > >Manuel Diaz Azpiroz >Dpt.
