Experimental Study of Packaging Materials Based on Acoustic Measurements Combined with Tensile Tests
Blekinge Institute of Technology, School of Engineering, Department of Mechanical Engineering2009 (English)Report (Other academic)
In this report, we investigated the variation between tension and fundamental frequency with respect to time, and at a constant strain rate. This was done for rectangular thin sheets under uniaxial tensile test and transverse vibration. Thin Paper (PPR), Low Density Polyethylene (LDPE) and laminate (PPR/LDPE/Al-foil) sheets were analyzed both within the elastic and plastic (which was investigated in this work) regions. The emphasis is on the linear relationship between the resonance frequency (in square) and the load.
