“…The aim of numerical analysis was to predict strength of material and to shorten the time needed for experimental material testing. The numerical study shown to be very reliable for some similar testings such as welded joints [11], bucket wheel boom hoist system [12], some composite materials [13] or even transmission gears [14] and beams [15]. Also, some interesting findings on this steel can be found in research of properties of HSS S690 at low temperatures [16].…”

With constant advancements in the field of construction engineering, there is a growing need for high strength construction steels such as the steel grade S690QL, which is analyzed in this paper. These steels should have good mechanical properties which would make the construction reliable and light. The steel grade S690QL is used for producing high responsible constructions such as cranes, dynamic loaded parts for millitary vehicles and battle assemblies, etc [1]. When complex constructions are made, especially the ones made of steels of wide cross sections, the steel is often heated (preheated, additionally heated and tempered), and the process engineers and designers often find themselves in a dilemma concerning the maximum temperatures allowed for this process. In the literature, wide ranges of these temperatures can be found, depending on the thickness. The aim of this paper is to determine experimentaly and numericaly the maximum working temperatures at which S690QL steel keep thier high strength values.In order to determine dependance of mechanical properties of the S690QL steel on the temperature, numerous investigations has been carried out [2][3][4][5][6][7]. Most of the investigations dealt with properties of base metal S690QL, but some papers show results of investigation of welded joints made of mentioned steel [2]. The aim of investigations was to determine

“…[1][2][3][4][5] Therefore, composite materials have been used in a wide range of applications such as the aerospace, automotive, defense, and sports industries. [6][7][8][9][10] Textile fabrics have long been known as ideal reinforcements for composite applications, due to their attractive intra-and inter-laminar strengths, damage tolerance, low cost, and versatile design potential. 11 Composite laminates are mostly used for impact resistance.…”

This study investigated the impact and post-impact behavior of different layer weft plain knitted composite materials based on modified ultra-high-molecular-weight polyethylene/epoxy composites. The modified ultra-high-molecularweight polyethylene weft plain knitted composites with 8, 12, 16 layers were prepared by vacuum-assisted resin transfer molding process and then subjected to impact and post-impact compression test. The impact properties were analyzed using the contact force-deflection and energy-time curves, and the post-impact compression was analyzed using the compression strength-strain curves. It can be obtained that the maximum contact force, absorbed energy, and residual compression strength after impact of the 16-layer specimen are 81.40%, 74.18%, and 73.25% more than those in the 8-layer specimen. respectively. According to the ultrasonic C-scan tests for the impact samples, the 16-layer specimen had the least damage area after the impact test, and the 8-layer composites damage area was 117.45% more than the 16-layer specimen.
