The tunneling of mechanical energy through a taut string is revisited in this paper in order to study tunneling times for this classical system. General properties of the group delay, the dwell time and the interference time are described. Moreover, we explain how to build string arrays with piecewise constitutive parameters that behave like quantum mechanical heterostructures with alternating well and barrier layers. The paradoxical Hartman effect is also analyzed. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.781 2020 PHYSICS, MULTIDISCIPLINARY 73 / 85 = 0.859 2020 Q4 T3 EDUCATION, SCIENTIFIC DISCIPLINES 40 / 44 = 0.909 2020 Q4 T3 0.42 2020 Physics and Astronomy (miscellaneous) 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Horta Rangel, Francisco A.
