  1. 16. Fracture Mechanics Applied in Thin Ductile Packaging Materials-Experiments with Simulations

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abdulfeta Jemal; Rahul Reddy Katangoori; [2011]
    Keywords : Mode I tensile loading; Continuum; Fracture; Fracture toughness; LEFM; MSYM. ABAQUS; FEM.;

    Abstract : Finding new or improving existing opening solutions for a package are important at Tetra Pak since the development of new polymers films influence the present package opening solutions. Knowing the general mechanical and fractural behavior of the package material is crucial for the understanding and prediction of the overall opening performance. READ MORE

  3. 17. ACOUSTIC MEASUREMENTS OF THE SLOW DYNAMICS OF THIN SHEETS.

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Kingsley Onyeka Ezeoma; Kai Yang; [2009]
    Keywords : Slow Dynamics; Relaxation; Recovery; Acoustic; Measurement; Laser-sensing; non-contact; LabVIEW.;

    Abstract : Based on the relationship between resonance and tension on thin sheets, an experimental approach was adopted to test the slow dynamic behaviour of Paper, Low Density Polyethylene (LDPE), the laminate of both and same laminate with Aluminium inclusive. We used a non contact acoustic excitation and non contact laser sensing. READ MORE

  5. 19. Vibration Based Techniques for Young's Modulus Determination and Permenant Deformation Assesment

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Viswanath Ramireddy; Mukarram Hussain; [2007]
    Keywords : Resonance frequency; material characterization; remote excitation; nondestructive testing; Mechanical Properties.;

    Abstract : This thesis work is devoted to low frequency vibration based method, with remote excitation and laser detection for nondestructive testing and characterization of sheet materials. By this method dynamic properties of different materials can be estimated from the measurement of the resonance frequency in flexural mode. READ MORE

  6. 20. A Pre-Study of the Tearing Behaviour of the Flexible Materials-towards Efficiency Packaging

    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Mohammed Jalaluddin Hyder; Hameeduddin Ahmed; [2006]
    Keywords : Tearing; Cohesive Zone; ABAQUS; Tensile Test; Finite Element; Essential Work of Fracture EWF theory; Mechanical properties; Experimental method; MTS;

    Abstract : In this thesis the tearing behaviour of flexible material is studied. A finite element model was built in ABAQUS and simulations were performed. The experimental tests were carried out to monitor the Load vs. Extension curve on single-tear specimen of Low Density Polyethylene (LDPE) and Paperboard. READ MORE
