This paper develops an experimental technique to evaluate the initial yield surfaces of metallic materials, as well study their evolution during plastic flow. The tracing is necessary for deriving and calibrating more robust phenomenological models directional distortional hardening. Such can be used characterize behavior structures experiencing complicated demanding loading modes, such multiax...

Through an improved characterization methodology, this work contributes to better prediction quality in composite forming simulations for unidirectional thermoplastic composites. A understanding of the behavior will aid adoption these lightweight materials aerospace applications. The bias extension method was implemented and applied cross-ply laminates from carbon fiber reinforced characterize ...

Abstract We infer the temporal changes in pressure sources that induced crustal deformation during 2018 Shinmoe-dake eruption using strain and tilt observations discern deep magmatic activity associated with early stage of this began approximately 19 h earlier than previously defined onset activity. Distinct were observed from around 09:00 on 6 March to 12:00 8 (JST), coincident lava outflow in...
