Limiting dome height (LDH) tests were used to evaluate the formability of laser butt welded blanks of the dual phase 980 steel in comparison with the base metal. Two different lasers were used: diode and Nd:YAG, giving a wide range of welding thermal cycles. A sharp decrease in LDH was observed in the welded specimens due to the formation of a softened zone in the outer heat affected zone. Soft...

The purpose of this study is to optimize the bonding method plywood suitable for cross-laminated timber (CLT) with as a core by analyzing flexural performance and failure mode according lamina species, in longitudinal direction, whether or not adhesive applied joint. In case Douglas fir layer, modulus elasticity decreased about 11.5% due bonding, rupture increased application method. optimal co...

The purpose of this study was to investigate the difference between tungsten inert gas (TIG) welding of austenitic stainless steel assisted by microparticle oxides and that assisted by nanoparticle oxides. SiO₂ and Al₂O₃ were used to investigate the effects of the thermal stability and the particle size of the activated compounds on the surface appearance, geometric shape, angular distortion, d...

BACKGROUND Repeated fracture of the denture base is a common problem in prosthodontics, and it represents a nuisance and a time sink for the clinician. Therefore, the possibility of increasing repair strength using new reinforcement materials is of great interest to prosthodontists. AIM OF THE STUDY This study aimed to evaluate the effects of incorporation of zirconia nanoparticles (nano-ZrO2...

Moso bamboo (Phyllostachys pubescens Mazei ex H. de Lebaie), one of the most commonly used species in China, is a strong and stiff material. In this paper, the manufacturing process for glued bamboo laminate (GBL) is presented. The mechanical properties of GBL (compression strength, bending, tension, and shearing) were tested. Results indicated that the mechanical properties of GBL were signifi...

Determination of stress strain state components of butt welded joint with a mild interlayer at elasto-plastic tension is presented in this paper. Function of normal transverse stresses distribution on the thickness of mild interlayer and equations for determination of the stress intensity maximum value in hard metal at elasto-plastic deforming are proposed. The longitudinal stresses of mild and...

The present study presents the influence of welding current, welding voltage, welding speed and external magnetic field on hardness of shielded metal arc welded mild steel joints. Mild steel plates of 6 mm thickness were used as the base material for preparing single pass butt welded joints. Speed of welding was provided by cross slide of a lathe machine, external magnetic field was obtained by...
