Abstract:
The problem of crack (tear) propagation in structural nets and fabrics is investigated. A theoretical solution which predicts the crack propagation behaviour under the effect of biaxial stress fields is presented. This was achieved by abstracting the most important interrelations from the Phenomena understudy and expressing them as a partial differential equation, which was solved to give particular solutions corresponding to a given boundary and initial conditions. The proposed expression was modified to account for the behaviour of coated fabrics under a uniaxial stress field. The scope of the investigation included other topics relevant to the crack propagation phenomena such as, the effect of joint slipping on the redistribution of stresses in structural nets. Experimental and analytical work was conducted to evaluate the reliability of the proposed expression and to explore its limitations. The results obtained were found to be in close agreement with the predicted crack propagation behaviour. The excellent correlation between the proposed expression and the different theoretical and experimental work previously published which apparently seemed to be contradictory, established the validity and the reliability of the proposed solution.
