Dowel Arthrodesis for Degenerative Arthritis of the Tarsometatarsal (Lisfranc) Joints
Foot & Ankle, 1986A late complication of fracture with dislocation involving the tarsometatarsal joints of the foot (Lisfranc fracture) is progressive degenerative arthritis and pain. A dowel-graft arthrodesis technique is described that uses percutaneous bone graft from the iliac crest supplemented by crossed-wire fixation.

Weather exposure durability of welded dowel joints
Holz als Roh- und Werkstoff, 2007A zigzag pattern of rotationally welded dowels across the interface of a butt joint between two wood planks, without any adhesive, was shown to yield joints presenting some resistance to weather exposure, although not of exterior grade type.

Application of Numerical Modelling to Dowel-Welded Wood Joints
Journal of Adhesion Science and Technology, 2010Numerical models using a 3-D finite element analysis method and the behaviour of dowel-welded wood joints are presented. Simulation results for step butt wood joints with two welded wood dowels under shear are analyzed and a good agreement with the experimental results is shown. Anisotropic elasto-plastic constitutive law with hardening associated with

Series II: Forestry Wood Industry Agricultural Food Engineering, 2021
In this work, the influence of the number of dowels and the option to place the dowels in the cross section of part on the bending moment capacity of heat-treated wood dowel joints was analysed. The joints, which were made of heat-treated ash, were tested by means of a universal testing machine.The ultimate failure load and the moment arms were used to

The Dowel Group Action in Jointed Concrete Pavement
Advanced Materials Research, 2012The wheel load transfer across a joints in concrete pavement is accomplished mainly by dowel bar system, dowels are installed in order to allow shear load transfer across slab joints. The dowel group action has been examined in this paper via from using of 3-D FE mode. Numerical model results are presented in four formats in this study, including shear

Tarsometatarsal Joint Arthrodesis with Trephine Joint Resection and Dowel Calcaneal Bone Graft
The Journal of Foot and Ankle Surgery, 2014Arthritis of the tarsometatarsal joints is a challenging problem to treat. It can cause chronic foot pain and functional disability. We present a surgical technique for tarsometatarsal joint arthrodesis using a trephine to resect the articular surfaces and a dowel plug of an autogenous calcaneal graft with locking plate fixation. The procedure has been

The Design of Plain Doweled Jointed Concrete Pavement
Proceedings of the International Conference on Concrete PavementsThis report explores the controversies and consensus on the use of dowel bars in jointed concrete pavements, focusing on medium to heavy truck traffic routes. Historically, dowels have been recognized for their role in load transfer at expansion joints and in long, reinforced slabs.

В работе предложено замковое соединение стального шпунта, выполненное в виде двух одинаковых профилей постоянной толщины, отличающиеся от известных конструкций замковых соединений тем, что профили выполнены замкнутыми, имеют квадратное или прямоугольное сечение с прорезями на одной из сторон для обеспечения входа одного профиля в другой и взаимного ...

Misalignment of Dowel Bars in Rigid Pavement Joints
Sustainable Construction Materials 2012, 2012The performance of concrete pavements depends to a large extent upon the satisfactory performance of the joints. Most jointed concrete pavement failures can be attributed to failures at the joint, as opposed to inadequate structural capacity (FHWA, November 30, 1990).
