Hello, I'm Kaustubh Garud ME design Student, Doing my ME project in Analysis of Adhesively bonded joint between composite laminates(static and Fatigue). Can we do that using hypermesh preprocessor and solver? Also, can we create cohesive elements or cohesive zone model using hypermesh ? Please help.

 

Thank You

    HI,

     

    Can you please provide details about adhesively bonded joint?

     

    You can model cohesive/glue in RADIOSS using PROP/CONNECT and MAT/CONNECT

    Laminate configuration : [90/45/-45/0]s

    total No. of plys : 8

    Ply thickness : 0.3125 mm

    Laminate thickness : 2.5 mm

    Geometry of laminate is given in figure.

    Adhesive length (l) : 25mm

    Adhesive region : 25*25 mm2

    Adhesive thickness : 0.1 mm2

    Tension test results are given in figure. I want  to model this in Hypermesh using cohesive zone and get load displacement matching the experimental results.

    For that cohesive zone parameters are required which can be extracted from 'Inverse method' ie. Trial and error in FEA

     

    Thank You
