Development of Multi‐Axial Fatigue Retrofits for Waterway Lock Gate Components [supporting dataset]
Abstract of the final report is stated below for reference: Many lock gates within the US have reached or exceeded their designed life. Due to the intensity of cyclic loads and the environment, fatigue cracks have become a prominent issue. The work presented in this report is an analytical and experimental investigation into multi-axial fatigue crack mitigation by the use of carbon fiber reinforced polymer (CFRP) capable of extending gate-component fatigue life until permanent repair can occur. Detailed finite element models are used to develop and validate CFRP retrofit geometries capable of mitigating crack propagation on generalized, scaled specimens as well as a detailed model of the pintle geometry itself. Additionally, experimental crack mitigation is conducted in an attempt to validate what is found through the finite element analysis (FEA) models.
