Abstract��Four-point bending test is part of the procedures for testing casing and tubing connections. Here established the mechanical model of four-point bending. The equipment for four-point bending test was designed and manufactured by the mechanical model. Finally we validated correctness of mechanical model and validity of the equipment by flexibility and strain-gauging method and contrasted the practicability between two testing method.
