摘要：NOVELTY - The method involves selecting to-be-tested standard sample material by a standard sample test J-R curve. Reference ductile fracture toughness of the standard sample is obtained to establish a true stress-true strain curve of a finite element model. A GTN model parameter is adjusted. Outer surfaces of the surface sample are constrained. A restraining sample uniform restriction parameter is calculated. A longitudinal coordinate is drawn to obtain an associated line. Ductility fracture toughness relation between inner and outer surfaces of uniform restraining material is determined. USE - Uniform restraining material inner surface and outer surface ductile fracture toughness relation determining method. ADVANTAGE - The method enables improving restraining effect and reducing test cost and operation complexity of multimedia data in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing an uniform restraining material inner surface and outer surface ductile fracture toughness relation determining process.'(Drawing includes non-English language text)'
