Abstract
A testing method for layered strength of Roebel single-strands is provided, which relates to the field of material strength testing technologies. The testing method includes: preparing multiple Roebel single-strands as multiple testing samples; preparing multiple anvil heads, and welding the multiple anvil heads and the multiple testing samples in one-to-one correspondence to obtain multiple samples for anvil tensile testing; performing a tensile test on each sample for anvil tensile testing based on a set temperature and a set test position, and calculating peak load data of each sample for anvil tensile testing in the tensile test; calculating strength values of the multiple Roebel single-strands based on the peak load data of each sample for anvil tensile testing, and fitting the strength values based on a Weibull distribution function to obtain strength statistical characteristics; and calculating strength degradation data of each of the multiple Roebel single-strands based on the strength statistical characteristics.
