Membrane type Mark III cargo containment system (CCS) is considered in this study to investigate its strength capability under applied loads due to liquefied natural gas (LNG) cargo. A rectangular plated structure supported by inner hull structure is exemplified from Mark III CCS according to classification society's guidance and it is assumed as multi-layered structure by stacking plywood, triplex, reinforced polyurethane (PU) foam and series of mastic upon inner hull structure. Commercially available general purpose finite element analysis package is used to have reliable FE models of Mark III CCS plate. The FE models and anisotropic failure criteria such as maximum stress, Hoffman, Hill, Tsai-Wu and Hashin taking into account the direction dependent material properties of Mark III CCS plate components and their material properties considering a wide variation of temperature due to the nature of LNG together form the strength analysis procedure of Mark III CCS plate. Strength capability of Mark III CCS plate is understood by its initial failure and post-initial failure states. Results are represented in terms of failure loads and locations when initial failure and post-initial failures are occurred respectively. From the results the basic design information of Mark III CCS plate is given.

“…For the assessment of fiber and matrix failure modes, the independent failure criteria proposed by Hashin [27] have been utilized. In order to identify fiber-matrix shear mode an expression described by Padhi et al [28] has been utilized. This expression actually refers to the interactive failure criteria proposed by Tsai in terms of a single tensor polynomial failure criterion by considering the failure index proposed by Tsai-Wu [29].…”

The present work deals with the numerical prediction of the post buckling progressive and final failure response of stiffened composite panels based on structural nonlinear finite element methods. For this purpose, a progressive failure model (PFM) is developed and applied to predict the behaviour of an experimentally tested blade-stiffened panel found in the literature. Failure initiation and propagation is calculated, owing to the accumulation of the intralaminar failure modes induced in fibre reinforced composite materials. Hashin failure criteria have been employed in order to address the fiber and matrix failure modes in compression and tension. On the other hand, the Tsai-Wu failure criterion has been utilized for addressing shear failure. Failure detection is followed with the introduction of corresponding material degradation rules depending on the individual failure mechanisms. Failure initiation and failure propagation as well as the post buckling ultimate attained load have been numerically evaluated. Final failure behaviour of the simulated stiffened panel is due to sudden global failure, as concluded from comparisons between numerical and experimental results being in good agreement.

“…One way to achieve this is the use of purely phenomenological models (e.g. [24,45,48,51,70]) which define the degradation of engineering constants directly based on FPF theories and experimental observations. Typically, these models are computationally less expensive and provide for easier parameter identification, but they are not necessarily thermodynamically consistent.…”

“…This way the layer is assumed to reach the final state of damage immediately instead of modeling damage evolution. Versions of this method include the total discount (all ply stiffnesses set to zero) [24], limited discount (only some moduli set to zero, depending on failure mode) [45], and residual property method (selected stiffnesses reduced to a non-zero value) [48,70].…”

In the present article, computational modeling of progressive damage in continuous fiber reinforced laminates is considered. After a general review of modeling approaches and experimentally observed behavior of laminates, the focus is laid on predicting non-linear laminate behavior by models based on continuum damage mechanics. The wide variety of continuum damage models is demonstrated by example of three different damage models from the literature which are described in more detail. Finally, a ply level damage model developed by the authors is presented. The model is based on brittle failure mechanisms postulated by Puck and is able to capture several characteristics of the damage behavior of laminates. Furthermore, this brittle damage model is extended to include plastic shear deformations. It is shown, that the extended model capturing brittle damage and plastic strains leads to significant improvements in the prediction of the non-linear laminate behavior.
