Product Code:SAE J2649
Title:Strain-Life Overload Fatigue Data File Format
Issuing Committee:Material Properties Committee
Scope:SAE data file format for exchanging controlled periodic overload data. The object of this SAE Standard is to provide a simple, common methodology for exchanging the data from periodic overload fatigue tests. These tests consist of a single large fatigue cycle followed by a larger number of smaller cycles. The overloads are fully reversed fatigue cycles while the smaller cycles share a common mean and amplitude【英文标准名称】:StandardTestMethodforObtainingandTestingDrilledCoresandSawedBeamsofConcrete
