Bolted Joints in Laminated Composites
Expressions were presented which can be used to estimate the strengths of continuous fiber reinforced composite laminates containing pin-loaded holes. The expressions apply to laminates containing either a single pin loaded hole, a single row of pin loaded holes, or two parallel rows of pin loaded holes.
متن کاملIdentification of Bolted Joints through Laser Vibrometry
We present a new technique for identifying the dynamics of bolted joints. The technique relies on the comparison of the overall dynamics of the bolted structure to that of a similar but unbolted one. The di!erence in the dynamics of the two systems can be attributed solely to the joint; modelling this di!erence in the dynamics enables us to construct a non-parametric model for the joint dynamic...
متن کاملBolted Timber Joints with Self-tapping Screws
The use of self-tapping screws with continuous threads in the joint area as a reinforcement to avoid splitting of timber members is studied. A theoretical model is developed to calculate the stress distribution around a pin-loaded hole in a timber joint, to predict brittle failure modes in bolted connections and to calculate the load in the reinforcing screws. Laboratory experiments on reinforc...
متن کاملAnalytical Modeling of Thermal Resistance in Bolted Joints
An analytical approximate solution is developed for predicting the thermal resistance of bolted joints between two square plates . of the same material but different thicknesses. The plates are assumed to have perfectly flat and smooth surfaces, and they are joined by a bolted connection at the center of the square, forming a concentric annular contact region at the interface. The entire surfac...
متن کاملStudy of Bolt Load Loss in Bolted Aluminum Joints
Bolted joints are used widely in mechanical design and represent a weak link in a system where loss of joint clamping force can lead to degraded product performance or human injury. To meet current market demands, designers require reliable material data and analysis tools for their industry specific materials. The viscoelastic response of bolted aluminum joints used in the small die-cast engin...
