Strength Prediction in CFRP Woven Laminate Bolted Single-Lap Joints under Quasi-static Loading using XFEM
This paper is concerned with modelling damage and fracture in woven fabric CFRP single-lap bolted joints that fail by net-tension. The approach is based on the assumption that damage (matrix cracking, delamination and fibre tow fracture) initiates and propagates from the hole in a self-similar fashion. A traction-separation law (based on physically meaningful material parameters) is implemented...
متن کاملStrength Prediction in CFRP Woven Laminate Bolted Double-Lap Joints under Quasi-static Loading using XFEM
The current paper is concerned with modelling damage and fracture in woven fabric composite double-lap bolted joints that fail by net-tension. A 3-D finite element model is used, which incorporates bolt clamp-up, to model a range of CFRP bolted joints, which were also tested experimentally. The effects of laminate lay-up, joint geometry, hole size and bolt clamp-up torque were considered. An Ex...
متن کاملContact Behaviour of Composite Laminate under Quasi-Static Indentation Load
A viable solution to the ever-demanding weight-saving target in aerospace industry is the replacement of conventional engineering alloys with composite materials in primary structures. A major concern to the effective use of composite laminates is the substantial reduction in the compressive strength when the contact force has exceeded the delamination threshold load (DTL). This paper focuses o...
متن کاملBrazilian Test for Tensile Failure of Anisotropic Shale under Different Strain Rates at Quasi-static Loading
Shale formations show obvious anisotropic characteristics in their mechanical properties due to pronounced bedding planes and natural fractures. This anisotropic behavior generally creates complex fracturing networks and is crucial to gas shale stimulation. Although much research has been done to study the anisotropic compression behaviors of shale with static and quasi-static strain rates, the...
متن کاملcontributing factors to the mechanical strength of cumin seed under quasi-static loading
the mechanical strength of cumin seed and the effects of moisture content, seed size, speed and direction of loading on the force and energy required to fracture cumin seed were investigated. the results showed that moisture and loading direction were significant at the 1% level on the force and energy required to fracture cumin seed. the effects of seed size on force and loading speed on energ...
