“…Currently, the most widely used analysis method for capturing delamination initiation and growth of CFRP composites is based on the framework of finite element method (FEM), such as cohesive zone element (CZE) and virtual crack closure technique (VCCT). Although these techniques have been successfully applied to many delamination problems of CFRP composites [6][7][8], they usually have to preset the delamination growth path, which is difficult for many real engineering problems. Besides, as stated in [9][10][11][12], these conventional analysis methods based on classical continuum mechanics require that the displacement field of body be continuously differential in space.…”

This study presents a two-dimensional ordinary state-based peridynamic (OSB PD) modeling of mode-I delamination growth in a double cantilever composite beam (DCB) test using revised energy-based failure criteria. The two-dimensional OSB PD composite model for DCB modeling is obtained by reformulating the previous OSB PD lamina model in x–z direction. The revised energy-based failure criteria are derived following the approach of establishing the relationship between critical bond breakage work and energy release rate. Loading increment convergence analysis and grid spacing influence study are conducted to investigate the reliability of the present modeling. The peridynamic (PD) modeling load–displacement curve and delamination growth process are then quantitatively compared with experimental results obtained from standard tests of composite DCB samples, which show good agreement between the modeling results and experimental results. The PD modeling delamination growth process damage contours are also illustrated. Finally, the influence of the revised energy-based failure criteria is investigated. The results show that the revised energy-based failure criteria improve the accuracy of the PD delamination modeling of DCB test significantly.

“…A VCCT and a self-adaptive grid moving scheme are proposed to predict the delamination growth process. Riccio et al 27 used VCCT-based FEM analyses on double cantilever beam (DCB) and end notched flexure (ENF) specimens to characterize the traction-separation laws. The tractionseparation laws are applied to composite structures containing inter-laminar damage modelled by cohesive elements.…”

L-shaped stiffened composite panels provide an efficient structure for engineering applications. However, they often produce delamination in the preparation and service process due to a series of factors. To study the effect of different types of delamination on the compressive strength of stiffened composite panels, ABAQUS finite element software was used in combine with the progressive damage subroutine user-defined field variable (USDFLD), and the finite element model was established based on cohesive theory to realize the prediction of the progressive failure process and strength of the stiffened composite panels. The results showed that the delamination of a stringer had a greater impact on the strength of the stiffened composite panels than did the debonding between the skin panel and a stringer and the delamination of the skin panel. The debonding delamination and delamination of a stringer exhibited delamination growth near the damage position during static compression, but delamination of the skin panel exhibited no delamination growth. The experimental results were in good agreement with the finite element simulation results, which verified the validity of the finite element model.

“…As far as delamination in the stiffened structures is concerned, based on the hump resonance principle the effect of nonlinear contact upon natural frequency of the stiffened composite plate with delamination of skin panel and/or debonding interfaces between skin panel and stiffeners is studied by Chen et al 21 A multidomain modeling technique was presented by Naganarayana et al 22 for modeling of the delaminated stiffened shell structures. Riccio et al 23 presented the simulation of skin-stringer debonding growth in the stiffened composite panels based on the virtual crack closure technique (VCCT) and cohesive zone model (CZM). The free vibration behavior of the rotating composite circular cylindrical shell with both circumferential and axial stiffeners based on energy method was carried out Zhao et al 24 while Jafaria and Bagheri 25 studied the free vibration of simply supported rotating cylindrical shells with circumferential stiffeners using Ritz method.…”

Effects of delamination on free vibration characteristics of laminated stiffened cylindrical shells with pretwist are analyzed by finite element method. The investigation is carried out using an eight-noded quadratic isoparametric shell element, which incorporates the transverse shear deformation and rotary inertia along with a three-noded beam element for the stiffener. The multipoint constraint algorithm has been included to guarantee the compatibility of deformation, equilibrium of resultant forces, and moments at delamination crack tip. The general dynamic equilibrium equation is derived from Lagrange’s equation of motion for moderate rotational speeds for which the Coriolis effect is neglected. The standard eigenvalue problem is solved utilizing QR iteration algorithm. The accuracy of the present formulation is validated with benchmark solutions is available in the literature. The present work concerns about the effects of delamination, fiber orientation, twist angle, stiffener depth-to-shell thickness ratio, and rotational speed on the fundamental frequency of shallow cylindrical shells with stiffener. Representative mode shapes for some typical case of the stiffened shell for different twist angles and rotational speeds are also presented.
