As an emerging advanced construction material, strain hardening cementitious composite (SHCC) has seen increasing field applications in recent years. Reliable data on tensile properties, including tensile strength and tensile strain capacity, are needed for structural design and for quality control. However, existing uniaxial tensile tests are relatively complicated and sometime difficult to im...

Current post-process heat treatments applied to selective laser melting produced Ti-6Al-4V do not achieve the same microstructure and therefore superior tensile behaviour of thermomechanical processed wrought Ti-6Al-4V. Due to the growing demand for selective laser melting produced parts in industry, research and development towards improved mechanical properties is ongoing. This study is aimed...

We examined macroscopically and microscopically 55 cadaver rotator-cuff tendons attached to their humeral heads to determine the distance between the edge of the articular cartilage and the tendon insertion of the supraspinatus (the width of the sulcus) and the score of regressive changes at the sulcus. In 33 specimens we measured the tensile strength. The width of the sulcus was correlated wit...

In this paper we give an account of applications of quantum-mechanical (first-principles) electronic structure calculations to the problem of theoretical tensile strength in metals and intermetallics. First, we review previous as well as ongoing research on this subject. We then describe briefly the electronic structure calculational methods and simulation of the tensile test. This approach is ...

Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. In the present study, statistical analyses are performed on some data col...

Pressurized water reactor (PWR) cores operate under extreme environmental conditions due to coolant chemistry, operating temperature, and neutron exposure. Extending the life of PWRs requires detailed knowledge of the changes in mechanical and corrosion properties of the structural austenitic stainless steel components adjacent to the fuel (internals) that are inherent to such conditions. This ...

objective:   the aim of this study was to evaluate the bond strength between metal brackets and non-glazed ceramic with three different surface treatment methods. materials and methods: forty-two non-glazed ceramic disks were assigned into three groups. group i and ii specimens were etched with 9.5% hydrofluoric acid. subsequently in group i, silane and adhesive were applied and in group ii, bo...

upgrading recycled fiber properties has been a constant concern in pulp and paper industry. in this respect many researches has been applied. the present paper has been considered the effect of amylase enzyme in pulping stage of old corrugated container (occ). also, pre-soaking of occ (first step of pre-soaking for 6 hours in 3% consistency in different ph(s) and second step of pre-soaking at 6...

BACKGROUND The use of long-chain polyunsaturated fatty acids has been studied in the context of healing and tissue regeneration mainly due to its anti-inflammatory, immunoregulatory and antioncogenic properties. Previous studies have demonstrated beneficial effects with the use of enteral immunonutrition containing various farmaconutrients such as L-arginine, omega-3, trace elements, but the in...

Purpose: The aim of the study was to evaluate micro-tensile bond strength and the conditioning patterns of a self-etching primer bonding system to un-etched (with extended priming) and etched ground fluorosed enamel. Materials and Methods: Extracted premolars were classified according to severity of fluorosis using Thylstrup and Fejerskov index (TFI: 0, normal; 1-3, mild fluorosis; and 4-6, mod...
