  • matrix crack initiation and progression in compositelaminatessubjected to bending and extension
    International Journal of Solids and Structures, 1999
    Co-Authors: Erik Adolfsson, Peter Gudmundson
    Abstract:

    An experimental investigation of matrix crack initiation and progression in glass/epoxy laminates of different stacking sequences is presented. The laminates have been loaded in extension and bending, and the degree of damage as function of the load has been recorded. The changes in certain elastic properties caused by the damage were also measured, and are compared to results from a previously developed approximate analytic model. An energy release rate resistance curve is adopted in an attempt to describe the initiation and progression of matrix cracks in the laminates. The amount of cracking is also viewed in relation to the Strain transverse to the fibres in the Ply under consideration, and the Ply stresses at the onset of cracking are calculated. The different damage evolution criteria are compared to the experimental results, and their validity and reliability are discussed. By use of the Ply Strain transverse to the fibres as a critical parameter for damage evolution, the load-deformation curves of the tested laminates are simulated taking damage progression into account.

  • prediction for progression of transverse cracking in cfrp cross Ply laminates using monte carlo method
    Advanced Composite Materials, 2017
    Co-Authors: Sota Onodera, Yoshiko Nagumo, Tomonaga Okabe
    Abstract:

    This study predicted transverse cracking progression in laminates including 90° plies. The refined stress field (RSF) model, which takes into account thermal residual Strain for plies including transverse cracks is formulated, and the energy release rate associated with transverse cracking is calculated using this model. For comparison, the energy release rate based on the continuum damage mechanics (CDM) model is formulated. Next, transverse cracking progression in CFRP cross-Ply laminates including 90° plies is predicted based on both stress and energy criteria using the Monte Carlo method. The results indicated that the RSF model and the CDM model proposed in this study can predict the experiment results for the relationship between transverse crack density and Ply Strain in 90° Ply. The models presented in this paper can be applied to an arbitrary laminate including 90° plies.
