Abstract The application of 2.5D woven composites (2.5DWC) in engineering structures has received increasing attention, but the mechanical behavior of the 2.5DWC notched structure (2.5DWC-NS) is not very clear, especially the effect of notch shapes. For this purpose, a full-thickness unit cell model, including its finite element model, of 2.5DWC is built in this work based on the actual mesoscale characterization of the material. Subsequently, the unit cell finite element model is spliced and mo...

Abstract null null The fatigue behavior of Fe44Mn36Co10Cr10 high entropy alloy (HEA) at room temperature and 300 °C was studied by in-situ SEM observation, electron back-scattered diffraction (EBSD) and crystal plasticity simulation. The microstructure evolution and deformation process was observed by in-situ SEM fatigue experiment. The misorientation and geometrically necessary dislocation (GND) density was analyzed by EBSD. A crystal plasticity finite element (CPFE) modeling method based on th...

Considering the difficulty of generating high quality meshes for the representative volume cell (RVC) of 2.5D woven composites (2.5DWC), a voxel-mesh full-cell model is developed in this paper. Herein, microscopic characterizations of 2.5DWC are performed, and the geometric relationship of the microstructure are established. For comparative analysis, six models are built, including a consistent-mesh full-cell model (CFM), three voxel-mesh full-cell models (VFM) with different mesh sizes, and a c...

Abstract In this paper fretting fatigue crack behavior in 1045 steel is studied by in-situ observation and finite element analysis. in-situ fretting fatigue experiments are conducted to capture real-time fretting fatigue crack formation and propagation process. The fretting fatigue tests under different load conditions are carried out, then the lifetime and fracture surface are obtained. The crack propagation rates under different loading conditions are measured by in-situ observations. With in-...

Abstract The effects of temperature and load on fretting fatigue induced geometrically necessary dislocation (GND) distribution in titanium alloy are studied by electron back-scattered diffraction (EBSD) in this paper. Fretting fatigue experiments under different temperature and load in TC11 titanium alloy are carried out and samples with small cracks are obtained. With Hough-based EBSD, the misorientation and GND densities induced by fretting fatigue are analyzed in both crack formation zone an...

Abstract In view of the large difference between the traditional unit-cell model (UCM) and the actual microstructure of 2.5D woven composites, which will affect the mechanical properties and failure behavior, a representative volume element (RVE) modeling strategy considering the randomness of weft cross-section (WFCS) is developed, and the established model is called statistical volume element (SVE) in this work. Based on the microscopy observation of warp cross-section (WPCS) and WFCS, some ge...

Abstract Elevated fatigue behaviors of resin matrix composites are considerable key to the application of aeroengine that requires fatigue resistance at elevated temperature. However, undeniably, very few studies are focused on this issue, thereby resulting in limitation applications of resin matrix composites in aeroengine components, i.e. blades and case. In this work, the fatigue responses of layer-to-layer 3D angle-interlock woven composites (2.5DWC) were experimentally and numerically studi...

The temperature-dependent mechanical behaviors of open-hole composite plates are essential for composite design and structures. Here, tensile experiments of shallow straight-link-shaped 2.5D woven composites (abbr. 2.5DWC) with/without a center hole are first conducted at different temperatures (20 °C, 180 °C and 240 °C). Failure modes are examined by scanning electron microscope (SEM). Thermal property of QY8911-IV resin is investigated by DMA analysis. It is noted for samples without the cente...
