RISOn Parametric Stability of a Nonconstant Axially Moving String Near Resonances
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stability of an axially moving string system subjected to parametric excitation resulting from speed fluctuations has been examined in this paper. The time-dependent velocity is assumed to be a harmonically varying ...
Comparison of Fatigue Life of AA2050-T852 and AA7050-T7452 Alloy Forgings at Different Orientations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study compares the fatigue performance between the AA2050-T852 alloy and AA7050-T7452 alloy traditionally used in aircraft structures. Rotating beam fatigue tests were performed on AA2050-T852 and AA7050-T7452 specimens ...
