Development of the plastic zone at the crack tip under cyclic loading in the middle-cracked tension specimen
Original language description
The paper deals with the development of the plastic zone size during cyclic loading. The analysis was carried out using finite element method. The three- dimensional model of M(T) cracked test specimen was discretized by hexahedral elements with fine mesh around the crack tip. The elastic/perfectly-plastic material with isotropic hardening was employed. Cyclic loading with coefficient of the cycle asymmetry was applied up to 100 cycles and the plastic zone area and the size in the direction of crack growth was monitored. The cyclic plastic zone size in the centre of the specimen, where plain strain prevails, remains approximately constant, but near the free sides, the size is reduced with increasing number of cycles and tends to form the shape and size of plain strain. The size development in the plain strain conditions in upwards part of the cycle can be described by power low with exponent ~4 for monotonic and cyclic zone as well.
