Development of mechanical analysis code (MACBECE) for TRU waste disposal

Mihara, Morihiro  ; Sato, Nobuyuki; Ono, Shintaro*; Morikawa, Seiji*

This report shows the capability, incorporated mechanical model and sample calculation of MACBECE. MACBECE incorporated the non-liner elastic model for cement-based material, the elasto- viscoplastic model considering swelling of bentonite-based material and the visco-elastic model reported by Okubo for host-rock. Furthermore, MACBECE can consider chemical transition of bentonite-based and cement-based materials.
