Offshore pipeline has a high level of bending deformation because of helical structure.The production process and the external loads can cause a cross-section ovalization.To predict the tension stiffn
Research on the acoustic stealth structures of submarines primarily strives for low frequency, pressure resistance, and broad frequency domain absorption.The high-quality acoustic stealth coating on s
In this paper, four types of local reinforcement schemes used in composite laminates bolted joints were studied.Through numerical method, a 3-D progressive failure analysis was implemented to analyze
In the description of nonlinear response of fiber-reinforced composites, the one-parameter plasticity model developed by Sun and Chen is the simplest one, including a single parameter that indicates t
MetallizationFRP composites have broadened their applications for functional purposes.The adhesive quality of the coating has significant influence on the performance and service life.Many remarkable
Accurate characterization of delamination damage and evolution plays a significant role in studying failure behaviors of composite laminates.In the present paper, acoustic emission (AE) and digital im
The novel fiber metal laminates based on aluminum-lithium alloy (NFMLs) were investigated to improve the stiffness and damage tolerance.The aluminum-lithium sheets were rolled from 2 mm to 0.3mm by co
To accurately simulate the response of a structure in high-speed crash and impact events, such as bird-strike, the strain-rate dependency of the materials should be considered.Explicit finite element
The electro-oxidation of thiourea[1-3] on gold electrode is found to possess complex dynamical processes that include interface reaction,chemical reaction and adsorption of products,by using electroch
