Band Gap Characteristics of Nonrotating Passive Periodic Drill String
Alsaffar Y.; Sassi S.; Baz A. ( American Society of Mechanical Engineers (ASME) , 2018 , Article)A new class of drill strings is investigated whereby strategically designed and placed periodic inserts are utilized to filter out the vibration transmission along the drill strings. Such mechanical filtering capabilities ... -
Band gap characteristics of periodic gyroscopic systems
Alsaffar Y.; Sassi S.; Baz A. ( Academic Press , 2018 , Article)The stop and pass bands (i.e. the band gaps) characteristics are determined for gyroscopic systems by developing an approach which is compatible with such class of systems which is based on the concept of Bloch wave ... -
Collapse behavior of thin-walled corrugated tapered tubes under oblique impact
Alkhatib S.E.; Tarlochan F.; Hashem A.; Sassi S. ( Elsevier Ltd , 2018 , Article)Thin-walled structures are used in safety applications such as automotive vehicles and locomotives because of their efficient energy absorption, light weight, and reduced manufacturing cost.
