Influence of Weld-Porosity Defects on Fatigue Strength of AH36 Butt Joints Used in Ship Structures
نویسندگان
چکیده
Experimental tests were carried out to assess the fatigue strength of four types welded joints, made AH36 steel and used for ship structures. The joints differ presence weld defects thickness value. Fatigue applying axial cyclic loads at a frequency 20 Hz stress ratio R = 0.5. temperature e increment specimen surface was detected during load application by means an infrared camera. analysis thermographic images allowed assessment both rapid method, S-N curve energy approach. Moreover, 3D computed tomography defective joints.

Influence of Post Weld Heat Treatment on Strength of Three Aluminum Alloys Used in Light Poles
The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. ...

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
The Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel
The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...
