1. Behaviour of hollow circular section with multiple perforations under compression, flexure and torsion
Abstract Effect of the presence of perforations on thin structure has been extensively investigated for decades. Various perforation parameters were investigated in past studies. However, study on thin cylinder with multiple perforations has not been carried out. In searching for lighter structural members, the concept of perforated hollow section has been i

2. Development and Evaluation of Calibration Procedure for a Force-Moment Balance Using Design of Experiments
Abstract To measure the aerodynamic and hydrodynamic forces and moments acting on scaled models in water and wind tunnel tests, multi-component strain gauge force and moment balance are usually used. Their performance and accuracy largely depends on the rig and calibration method, including the load table (design matrix) and analysis of experimental data. In

3. Load-Application Devices: A Comparative Strain Gauge Analysis
Considerando os valores relativamente pequenos utilizados em odontologia para os ensaios de carregamento verticais axiais, foi desenvolvido um dispositivo de aplicação de carga (DAC) para substituir a máquina de ensaios universal (EMIC). O objetivo deste estudo foi desenvolver um DAC e compará-lo com a EMIC por meio da utilização de carregamentos axiai

4. Strain analysis of different diameter Morse taper implants under overloading compressive conditions
The aim of this study was to evaluate the amount of deformation from compression caused by different diameters of Morse taper implants and the residual deformation after load removal. Thirty Morse taper implants lacking external threads were divided into 3 groups (n = 10) according to their diameter as follows: 3.5 mm, 4.0 mm and 5.0 mm. Two-piece abutments

5. Effects of threaded post placement on strain and stress distribution of endodontically treated teeth
The aim of this study was to evaluate the effect of parallel and tapered threaded post placement on the strain and stress distribution of endodontically treated teeth. Fifteen bovine incisors were sectioned 15 mm from their apices, endodontically treated, and divided into three groups (n = 5) according to three di

7. Analysis of marginal misfit and strain gauge in implant-supported frameworks using straight line and offset placement with different copings under axial and non-axial load / Análise extensométrica e do desajuste marginal de infra-estruturas implanto-retidas nas configurações linear e compensada com diferentes coifas sob aplicação de cargas axiais e não axiais
O objetivo neste estudo in vitro, foi analisar microscopicamente o desajuste vertical e passivo e quantificar a deformação usando análise de extensometria durante aplicação de carga axial e não-axial em prótese parcial fixa implanto-suportada de três elementos, variando a posição dos implantes, linear (L) ou compensada (C) e o tipo de coifa protét

8. Avaliação da deformação média gerada nos intermediários e na região peri-implantar durante as etapas de confecção da prótese parcial fixa parafusada: análise com strain gauges / Evaluation of abutment and simulated bone tissue mean deformation around dental implants, during fabrication stages of screw-retained fixed partial prostheses: strain gauges analysis
A adaptação passiva e estabilidade têm se tornado os dois pré-requisitos de maior importância na escolha dos materiais e técnicas de confecção em prótese implantossuportada. A proposta deste trabalho foi avaliar, com auxílio dos strain gauges ou extensômetros lineares elétricos, a deformação média ocorrida nos intermediários e na região peri

10. Machined and plastic copings in three-element prostheses with different types of implantabutment joints: a strain gauge comparative analysis
OBJECTIVE: Using strain gauge (SG) analysis, the aim of this in vitro study was quantify the strain development during the fixation of three-unit screw implant-supported fixed partial dentures, varying the types of implant-abutment joints and the type of prosthetic coping. The hypotheses were that the type of hexagonal connection would generate different mic

11. Analise fotoelastica e extensometrica das tensoes induzidas por estruturas de protese sobre implantes fabricadas pelas tecnicas monobloco, soldagem de borda e metodo CAD/CAM / Photoelastic and strain gauge analysis of tensions induced over implant superstructures manufactured through one-pierce technique., bolder soldering and CAD/CAM method, border soldering and one-piece technique
The lack of passivity of the implant supported prosthesis may lead to mechanical and biological disorders over the implants. By the photoelastic and strain gauge analysis, the purpose of this research was to evaluate the stress over the implants after tightening the prosthesis superstructure over five dental implants. A stainless steel matrix was manufacture

12. Influência do tipo de retentor intra-radicular e da radioterapia na deformação, resistência e padrão de fratura de diferentes dentes tratados endodonticamente
The aim of this in vitro study was to evaluate the influence of post type and the radiotherapy effect on strain, fracture resistance and fracture pattern for different teeth endodontically treated. 160 human teeth were selected (n=40): In, incisives; Ca, canines; Pm, pre-molar e Mo, molars. After the endodontically treatment, half of samples (n=20) was subje
