Yao, Liaojun (author), Chuai, Mingyue (author), Lyu, Zhangming (author), Chen, Xiangming (author), Guo, Licheng (author), Alderliesten, R.C. (author)Methods based on fracture mechanics have been widely used in fatigue delamination growth (FDG) characterization of composite laminates. These methods are based on the similitude hypothesis. It is therefore important to have appropriate parameters to well represent the similitude, which is useful for fatigue delamination test standard...journal article 2024

Ji, C. (author), Hu, Jiqiang (author), Alderliesten, R.C. (author), Yang, Jinchuan (author), Zhou, Zhengong (author), Sun, Yuguo (author), Wang, Bing (author)This paper aims to illustrate the effect of the impact damage on fatigue behavior of CF/PEEK-titanium hybrid laminates. To achieve this end, a fatigue life model was proposed to predict the S–N curves of the laminates at various initial impact energy levels and stress ratios based on the energy dissipation approach. The energy dissipation...journal article 2024

Yao, Liaojun (author), Wang, Jiexiong (author), He, Yonglyu (author), Zhao, Xiuhui (author), Chen, Xiangming (author), Liu, J. (author), Guo, Licheng (author), Alderliesten, R.C. (author)Fatigue delamination growth (FDG) is an important failure in composite structures during their long-term operations. Hygrothermal aging can have significant effects on interlaminar resistance. It is therefore really necessary to explore FDG behavior in composite laminates with hygrothermal aging. Dynamic mechanical thermal analysis (DMTA),...journal article 2024

Tao, N. (author)THICK composite materials, e.g., thickness of more than 50 mm, are increasingly being used across diverse industry sectors owing to their significant advantages of weightsavings, superiormaterial properties and load-carrying capability. These materials tend to be adopted in safety-critical applications such as large primary or secondary load...doctoral thesis 2023

Huo, L. (author)Fibre-reinforced polymer composite laminates are used extensively nowadays in various applications due to their superior mechanical properties. However, a great weakness of composite laminates is their susceptibility to out-of-plane concentrated loading (which can be broadly divided into quasi-static indentation and impact) owing to their weak...doctoral thesis 2023

Alcaraz, Mathilde (author), Alderliesten, R.C. (author), Mosleh, Yasmine (author)Fibre metal laminates (FML) were originally developed as a hybrid material, to create synergy between the impact resistance of metals and excellent fatigue and corrosion resistance of fibre reinforced polymers, and to overcome the shortcomings of monolithic materials. Yet, the scope of the FML concept is predominantly limited to GLAss REinforced...abstract 2023

(author)This work aims to improve the flexural behaviour of unidirectional fibre-reinforced laminates by means of coupling an optimization procedure for quasi-isotropic configurations with the design space opened by dispersed-ply orientations. The design approach consists of finding suitable alternatives to traditional laminates (with fibre...journal article 2023

Takali, Farid (author), Nirwal, Sonal (author), Othmani, Cherif (author), Groves, R.M. (author)It has been shown that the roots of guided waves in laminate plates produced by the ordinary differential equations (ODE) approach may not hold under to some computational conditions. A particular drawback of the 2D formulation of the ODE approach is the lack of reliability in the case of unidirectional laminates due to the decoupling...journal article 2023

Liu, S. (author), Sinke, J. (author), Dransfeld, C.A. (author)The bias-extension test is one of the test methods to characterise the intra-ply shear behaviour of continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For the determination of the major mechanical properties of metals, often a uniaxial tensile test is used. Combination of these two methods for the...journal article 2023

Bedon, Chiara (author), Louter, P.C. (author)Purpose: Glass material is largely used for load-bearing components in buildings. For this reason, standardized calculation methods can be used in support of safe structural design in common loading and boundary conditions. Differing from earlier literature efforts, the present study elaborates on the load-bearing capacity, failure time and...journal article 2023

Hofman, P. (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)In this work, a recently proposed high-cycle fatigue cohesive zone model, which covers crack initiation and propagation with limited input parameters, is embedded in a robust and efficient numerical framework for simulating progressive failure in composite laminates under fatigue loading. The fatigue cohesive zone model is enhanced with an...journal article 2023

Moazzami, Mostafa (author), Ayatollahi, M. R. (author), Akhavan-Safar, Alireza (author), Teixeira De Freitas, S. (author), da Silva, Lucas F.M. (author)When a composite laminate is subjected to humidity, moisture diffusion occurs depending on the number and thickness of the lamina. Water diffusion changes the mechanical response of laminates and usually causes a significant reduction of the mechanical properties of the composite specimens in ocean structures. One of the most important...journal article 2023
