This work explores the postbuckling behavior of a marine stiffened composite plate in presence initial imperfections. The imperfection shapes are derived from buckling mode and their combinations. Thereafter, these applied to model, nonlinear large deflection finite element progressive failure analyses performed ANSYS 18.2 software. Hashin criterion is employed model plate. effect geometric on ...

in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...

breakwaters are the important and the costly ones of the marine structures. composite breakwater is one of the common types in the world. because of the sensitivity of composite breakwaters to environmental conditions, also construction costs, difficulty of repair and maintenance and importance of equipments on and behind the breakwater, design of composite breakwater must be very accurate. goa...

In the dilute limit Eshelby's inclusion theory captures the behavior of a wide range of systems and properties. However, because Eshelby's approach neglects interfacial stress, it breaks down in soft materials as the inclusion size approaches the elastocapillarity length L≡γ/E. Here, we use a three-phase generalized self-consistent method to calculate the elastic moduli of composites comprised ...

With the development of urban underground space and increased infrastructure functions, both scale engineering construction difficulties have globally. In structures in soft strata, especially coastal areas, limited bearing capacity foundations poses a significant challenge. The composite pile technologies employing an organic combination rigid andthe flexible column can enable efficient ground...

Abstract The article presents a technique for process-induced residual strain modeling thermoset composite material parts. model takes into account the mechanical and thermal contact between part mold. is implemented in ABAQUS software using user subroutines. Using technique, it possible to clarify distribution of heat transfer coefficient on surface mold CFD method. Distribution coefficients a...
