Analysis of the torsional mode T(0,1) propagating in a bending pipe
(2018)
Conference lecture
Open AccessIn operation, some structural members are subjects to bending conditions. Velocity variations of guided waves propagating in a stressed specimen are expected due to the acoustoelasticity effect. In this work, a numerical ... -
A new damage model for structures subjected to cyclic loads
(2010)
Conference report
Restricted access - publisher's policyThe structures subjected to dynamic loads often show alternative tensioncompression states stress; in such a case, even if certain damage (fracture) is reached during the tension cycle, the structure should maintain its ... -
