We describe in this article a modified multilaminate model which takes into account matrix K|US~Hgv
elastoplasticity between weakness planes. The proposed model combines the multilaminate [$^A@bqk
model described in [1] and the general plastic yield surface of Men´etrey & Willam [2] and 10?qjjb&
generalizes both. XjxPIdX_H
The model’s performance is validated on selected benchmark problems and shows a good ^/k,
correlation with results available for comparison. The proposed model is believed to reproduce =9^Q"t4
more closely the behavior of rock.
