Tension Performance of Metal-Plate Connected Joints of Chinese Larch Dimension Lumber

Tension tests of metal-plate connected (MPC) joints for Chinese larch (Larix gmelinii (Rupr.) Rupr.) were conducted in four orientations. Loaddeflection curves were obtained for each MPC jointed specimen. Ultimate tension load, translation stiffness, stiffness at large slip, and failure modes for each specimen were obtained. A Foschi 3-parameter model was found to fit the load-deflection curves...

Shear Strength of Rock Joints Based on Quantified Surface Description

One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

Determination of Screw Withdrawal Strength of Heat- Treated and Reinforced Laminated Veneer Lumber

The withdrawal resistance of screws in heat-treated and reinforced laminated veneer lumber (RLVL) was determined in the radial, tangential, and transverse directions. For this reason, laminated veneer lumber (LVL) and RLVL with carbon fibers were produced from heattreated oak (Quercus petraea (Liebl.)) veneers using phenol formaldehyde as the adhesive. Wood samples were heat-treated at 140, 170...

Microstructure and shear strength of Sn37Pb/Cu solder joints subjected to isothermal aging

Keywords: Shear strength Microstructure Single-shear lap joint Intermetallic compound (IMC) Aging a b s t r a c t The effects of isothermal aging on the microstructure and shear strength of Sn37Pb/Cu solder joints were investigated. Single-lap shear solder joints of eutectic Sn37Pb solder were aged for 1–10 days at 120 °C and 170 °C, respectively, and then loaded to failure in shear with a cons...

Camera Based Lumber Strength Classification System

In this paper, a new camera based lumber strength classification solution using solely knot features is presented. Two alternative classifiers, k-NN and SVM, are applied to classifing pinewood boards based on their breaking strength. Features for classification are formed using knot properties, which are extracted from four sides of the board using machine vision algorithms. Extracted propertie...
