Fracture toughness (KIc) refers to the ability of a material containing a crack to resist fracture.Specifically,fracture toughness testing characterizes resistance to fracture in a neutral environment with a sharp crack,and is one of the most important properties ofWhat is use of Fracture Toughness (in Mode-I,II, III According to ASTM D5045-14,for calculation of KIC (fracture toughness) the maximum load should be in kN.I get a value of 186 N for epoxy resin.After conversion to kN it becomes 0.186 kN.Westmoreland Mechanical Testing and Research,Inc.World Leader in Materials Testing.Established in 1967 and headquartered in Youngstown,PA,approximately 35 miles east of Pittsburgh,PA; Westmoreland Mechanical Testing Research,Inc.was founded on the principles of innovation,excellence and quality.WMTRs never ending commitment to its customers is strongly supported by a dedicated and enthusiastic staff.
