Bolted 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 کاملSelf-tapping Screws as Reinforcement Perpendicular to the Grain in Timber Connections
The use of self-tapping screws with continuous threads as a reinforcement to avoid splitting of members in connections with dowel-type fasteners was studied in two projects carried out at the Universities of Nottingham and Karlsruhe. The reinforced specimens showed a very ductile failure mode whereas the non-reinforced specimens failed in a brittle way. Although the reinforced specimens also sh...
متن کاملUse of self-tapping metal screws for temporary fixation of a resorbable plate system in maxillofacial surgery.
Resorbable plate systems have been used in maxillofacial surgery to obviate the need for plate removal. However, resorbable plates and screws are very costly, and refixation with additional screws may be necessary when reduction or repositioning of the bone segment is inaccurate. Here we report the use of self-tapping metal screws for temporary fixation of a resorbable plating system in maxillo...
متن کاملSelf-rehabilitation with a game
We designed and evaluated a whack-a-mole (WAM) style game (see Figure 1) in a clinical randomized controlled trial (RCT) with reminder-assisted but self-initiated use over the period of a month with 43 participants from a post-lesion pool. While game play did not moderate rehabilitative progress indices of standard neuropsychological control tests, it did significantly improve in-game performan...
متن کاملEffect of Pilot Hole Tapping on Pullout Strength and Insertion Torque of Dual Core Pedicle Screws.
OBJECTIVE To evaluate the influence of pilot hole tapping on pullout resistance and insertion torque of pedicle screws with a conical core. METHODS Mechanical tests using a universal testing machine were performed on pedicle screws with a conical core that were inserted into pedicles in the fifth lumbar vertebra of calves. The insertion torque was measured using a torque meter with a capacity...
