Composite polymeric materials have exhibited significant advantages when operating in hostile conditions such as the marine environment. However, there is a lack of information concerning three-dimensional variations induced by prolonged exposure to seawater composite structures and their impact on fatigue performance. Thus, this study aims investigate effects long-term natural both strength chemical changes GFRP laminates. Fatigue tests were conducted under uniaxial cyclic loading at stress...
Composite materials are exposed to a range of hostile environments with consequent degradation in terms mechanical properties. However, the bibliography is not sufficient establish full knowledge about effect on This work intends study response flexural and low velocity impact glass fibre/epoxy composite after immersion two different acid solutions, hydrochloric sulphuric acid. These solutions affect significantly strength, however, was responsible for worst results. The maximum load elastic...
Objective: The objective of this review will be to synthesize the best available evidence on fathers’ lived experiences fatherhood during child’s first 1000 days life. Introduction: Involved and caring is crucial for healthy cognitive, physical, social, emotional development children; however, a challenging process most men. It characterized by profound changes that require new identity assumption roles within family. Understanding adult stage life can provide valuable knowledge families,...
The gold standard materials used for frameworks of full-arch implant-supported fixed prostheses (ISFPs) have traditionally been metal alloys, but recently, high-performance polymers such as polyetherketones and fibre-reinforced resins gaining popularity despite the lack evidence load-bearing capacity. aim present study was to evaluate displacements strains milled polymeric ISFPs using 3D digital image correlation. Methods: Twelve were from four (three per group): polyetheretherketone (PEEK),...
This work aims to compare the hardness (H) and roughness (Ra) of glass/epoxy composites after being exposed various hostile environments, which is possible because constituents are always same. Considering stacking sequence [452, 902, -452, 02]s, increases for all solutions up a certain exposure time, from it decreases longer immersion times. For same sequence, had its highest increase (around 44.5%) alkaline solution 36 days immersion, while decrease 25%) occurred mortars 30 exposure. [02,...
The main purpose was to evaluate the in vitro adhesion strength of direct and semi-direct composite resin restorations dentin, when same adhesive system is applied, using microtensile testing (μTBS) observe most recurrent types failure different groups. For this study, 16 intact human mandibular molars without microscopic evidence lesions were randomly divided into two test groups, according restoration strategy: (DR) (SR). both restorative strategies, (Clearfil SE Bond 2, Kuraray, Tokyo,...
Composite laminates have been used in the most diverse engineering fields, which they are often subject to multi-impacts. Typical examples of these phenomena found wind energy industry. However, several studies focused on this subject, but involve events with same level. Therefore, work intends study multi-impact behaviour composite as well verify if a linear damage accumulation law can predict life. For purpose, low-velocity impact tests were carried out energies 4 J, 6 8 J and 10 J. From...
This paper studies the monotonic and fatigue behaviour of notched glass fibre-reinforced polymers after long-term exposure in seawater. Uniaxial quasi-static tensile tests uniaxial stress-controlled cyclic were carried out for different immersion times, ranging from 0 days to 910 days, using rectangular cross-section specimens with a central hole. The geometric discontinuity was monitored, via digital image correlation, better understand damage accumulation process fracture mechanisms. A...
Fiber-reinforced polymer composites are frequently used in marine environments which may limit their durability. The development of accurate engineering tools capable simulating the effect seawater on material strength can improve design and reduce structural costs. This paper presents a numerical-based approach to predict stress–strain response fiber-reinforced exposed different immersion times, ranging from 0 900 days. A three-dimensional numerical model has been implemented using static...
