Influence of notch shape on the quasi-static tensile behavior of 2.5D woven composite structure

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...
