摘要：

Influences of cracking of the coated DyBa2Cu3O7-delta superconducting layer in composite superconductor under applied tensile strain on V(voltage)-I(current) curve, critical current and n-value were studied experimentally and analytically. The measured variations of V-I curve and critical current with increasing applied strain were described well by the modeling analysis. Also, the variations of shunting current with increasing imposed current and also with extension of cracks were revealed, from which the influences of shunting current on the variation of n-value with current were elucidated.
