Attend a seminar exploring the modern revival of cantilever bending techniques for high-throughput creep testing in materials science. Learn how position-sensitive strain measurements through image correlation can be coupled with varying stress in bent cantilevers to capture multiple stress-strain-time histories in a single test using samples as thin as 1 mm. Discover the evolution of this century-old technique and its applications to increasingly complex practical situations, starting with classical steady-state creep in simple materials and extending to complex metallurgical and ceramic systems displaying tension-compression asymmetry, as well as inhomogeneous systems like weldments and sandwich structures. Understand how stress evolution in creeping beams can be managed through invariant or skeletal points, postulated over 60 years ago, to recover effective uniaxial behavior from single experiments. Explore practical applications including residual life estimation of in-service steam turbine boiler tubes, rapid correlation of process variables with creep properties in additively manufactured alloys, and analysis of micro-textured regions in titanium alloys implicated in dwell-fatigue failure of aerospace components. This Henry Royce Institute seminar is presented by Prof. Vikram Jayaram from the Indian Institute of Science in India.
