Research on the Restraint of Large-scale Rigid Sample Cracking Test

The restraint of large-scale rigid sample cracking test is studied through the finite element computation and test in the paper. The simulation results agree well with test results. The results show that the restraint is maximum in the middle of practice weld,is minimum at the both ends of weld,is maximum at the position of strengthening rib,and diminishes gradually at the position away from the strengthening rib.
