RISNonlinear Behavior of Helmholtz Resonator With a Compliant Wall for Low-Frequency, Broadband Noise Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low-frequency sound attenuation is often pursued using Helmholtz resonators (HRs). The introduction of a compliant wall around the acoustic cavity results in a two degrees-of-freedom (2DOF) system capable of more broadband ...
Pressurized Infusion: A New and Improved Liquid Composite Molding Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vacuum-assisted resin transfer molding (VARTM) has several inherent shortcomings such as long mold filling times, low fiber volume fraction, and high void content in fabricated laminates. These problems in VARTM mainly ...
