25. Impact responses of slender composite plates for bird-strike testing of fan blades
Abstract Bird-strike failure of fan blades is one of the basic challenges for the safety of aircraft engines. Simplified slender blade-like plates are always used to evaluate the impact-induced damage mechanism at design stage. One undesirable issue is the failure at the root of clamped slender plates, which cannot recover the real case of twisted blades. Fo

26. Large deflection and initial instability analysis of anisotropic plates by the generalized finite element method
Abstract This paper presents investigations laminated plates under moderately large transverse displacements and initial instability, through the Generalized Finite Element Methods - GFEM. The von Kármán plate hypothesis are used along with Kirchhoff and Reissner-Mindlin kinematic plate bending models to approximate transverse displacements and critical bu

27. New nonlinear solution of nearly incompressible hyperelastic FGM cylindrical shells with arbitrary variable thickness and non-uniform pressure based on perturbation theory
Abstract In this paper, nonlinear analysis of thick cylindrical shells with arbitrary variable thickness made of hyperelastic FGM with radially variation of material properties in nearly incompressible state under non-uniform pressure loading is presented. Thickness and pressure of the shell vary in axial direction by linear and/or nonlinear functions. The g

28. A simple spline finite strip for buckling analysis of composite cylindrical panel with cutout
Abstract In this study, a new sub-parametric strip element is developed to simulate the axially loaded composite cylindrical panel with arbitrary cutout. For this purpose, a code called SSFSM is developed in FORTRAN to analyze the buckling of panels. The first order shear deformation theory is used to form the strain-displacement relations. Spline and Lagran

29. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

30. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

31. DESIGN OF EXPERIMENTS USED IN COMPUTER TRIALS: A SUPPORTIVE METHOD FOR PRODUCT DEVELOPMENT
ABSTRACT The study proposes the development of a framework that can take advantage of the Design and Analysis of Computer Experiments (DACE) more efficiently. The need for rapid product development cycles creates a demand for tools that aid in decision making. One of these tools is Computer Aided Engineering which uses the Finite Element Method that requires

32. Computational algorithm for the verification of reinforced concrete sections in fire situation
Resumo As estruturas de concreto armado podem ter sua capacidade resistente reduzida devido à degradação de suas propriedades mecânicas com a temperatura, aumentando o risco de colapsos estruturais. Assim, o dimensionamento de uma estrutura deve considerar seu comportamento em temperatura ambiente e em situação de incêndio (ABNT NBR 14432:2001). Neste

33. The role of bondline thickness on mechanical properties of bio-based polyurethane
ABSTRACT Bio-based adhesives have been largely applied on several applications in many industrial areas, including automotive and laminated food packaging. Polyurethanes (PU) occupy a leading position among the most used bio-based polymers due to their large range of properties and application versatility. Recent works reported that PU obtained from castor o

34. Effect of surface roughness and lubrication on the friction coefficient in deep drawing processes of aluminum alloy aa1100 with fem analysis
ABSTRACT Friction between the interface workpiece and tooling has considerable importance in sheet metal forming operations; an accurate description of the friction is necessary to analyze and design new workpieces and tooling. This work suggests a methodology to determine and evaluate the mean coefficient of friction (COF) using the Finite Element Method (F

35. Uma abordagem experimental e numérica para determinação de curvas de compressão para concreto simples e reforçados com fibras de aço
RESUMO A curva tensão-deformação do concreto é importante para o dimensionamento de estruturas, pois por meio dela é possível obter sua resistência à compressão, sua deformação de pico, o módulo de elasticidade e a tenacidade do concreto. Entretanto, essa é uma propriedade que não é comumente determinada nos ensaios de controle de qualidade do

36. Electromagnetic Core Analysis of a DFIG State-Feedback Power Controller
Abstract The energy demand by modern society grows every day that allied with sustainable development requires the use of alternative sources in the new energy matrix. In this context, the wind energy as source by using a doubly-fed induction generator stands out due to its operational savings but still faces some conflicts in its power control. This paper p
