Two-dimensional quasi-static delamination in composite laminates under Mode-I and Mode-II conditions
Fiber-polymer composites consist of a polymer matrix and reinforcing fibers made of various materials. These composites exhibit exceptional properties, such as a high strength-to-weight ratio and excellent corrosion resistance, which has led to their incre ...
EPFL2024Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Existing standards for delamination tests on composite materials typically employ one-dimensional (1D) beam specimens. However, such specimens may not represent real delamination scenarios in composite structures, where cracks tend to propagate in two dime ...
London2024Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Delamination in real composite structures, which generally tends to grow in two-dimensions, sometimes cannot be appropriately represented by the widely accepted test methods where one-dimensional (1D) beam specimens are typically employed. In order to comp ...
2024Web buckling mechanism of pultruded GFRP bridge deck profiles subjected to concentrated load
Congzhe Wang, Yun Sun, Yuqing Liu
The web's local buckling is a major failure type of pultruded glass fiber-reinforced polymer (GFRP) bridge deck subjected to concentrated wheel loads. Three kinds of external actions-that is, in-plane shear force, local compressive force and bending moment ...
ELSEVIER SCIENCE INC2021Numerical modeling of two-dimensional delamination growth in composite laminates with in-plane isotropy
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
The two-dimensional (2D) delamination growth in fiber-reinforced polymer (FRP) laminates with in-plane isotropy under Mode I loading condition was numerically investigated using finite element analyses. Two sizes of plate models were developed, focusing on ...
