Analysis of effects of crack closure in shells
Engineering Fracture Mechanics, 1989Abstract The effect of crack closure in a shell was studied using the finite element method. Elastic open cylindrical shells, containing through-wall-thickness stationary cracks under bending loads, were considered. Crack closure was modeled using the line closure model.

Effect of Crack Closure on Quantitative ECT Inspection of Closed Fatigue Cracks
2008In this paper, the feasibility to apply a closed fatigue crack as a substitute of a Stress Corrosion Crack (SCC) is investigated aiming at applications to ECT crack sizing. Several testpieces of closed fatigue cracks are fabricated, and ECT signals are measured after selected bending loads being applied to close the crack.

The effect of pre-strain on fatigue crack growth and crack closure
Engineering Fracture Mechanics, 1976Abstract A single pre-strain ( ϵ = 0.03 ) applied to 2024-T3 material raised the static yield strength from 428 to 480 MN/m 2 . The growth rate of a fatigue crack in the pre-strained material was about twice as large as in the material that was not pre-strained.

The effect of overloads on threshold and crack closure
International Journal of Fatigue, 1985Abstract The effect of tensile and compressive overloads on the threshold stress intensity level and crack closure behaviour of one aluminium alloy and three steels has been investigated. A few tensile overloads significantly decreased the crack propagation rate and increased the threshold stress intensity.

Effective Concrete Crack Closure Through Innovative Hybrid PET Tendons
Proceedings of the Cardiff University School of Engineering Research Conference 2024The article delves into the enduring challenge of cracking in concrete structures, examining innovative solutions, with particular emphasis on the development and assessment of a novel Tendon (the Side PET Hybrid Tendon (SPHT)). Traditional approaches to crack closure often prove inadequate in terms of both effectiveness and cost efficiency.
