Mechanical behavior of composite materials using the finite element analysis

Abstract

Abstract.A finite element analysis software has been used in order to determine several mechanical properties for samples made from unidirectional composite materials. Plates from reinforced unidirectional fiber glass polymer composites obtained by compression hand lay-up process were studied.Tensile tests were performed upon samples with different number and orientation of the composite ply layup.

Numerical simulation of poly(lactic acid) polymeric composites reinforced with nanofibrillated cellulose for industrial applications

“…Refinements were used to reduce error of approximation of the finite element model, which are ways of increasing the degrees of freedom of the elements in a model, to reduce error of discretization in subsequent mesh convergences, applying different forms of elements, other than triangular, such as follows: quadrilateral, tetrahedral, hexahedral. [ 25–27 ]…”

“…Refinements were used to reduce error of approximation of the finite element model, which are ways of increasing the degrees of freedom of the elements in a model, to reduce error of discretization in subsequent mesh convergences, applying different forms of elements, other than triangular, such as follows: quadrilateral, tetrahedral, hexahedral. [25][26][27] The choice of material for a specific application must, initially, consider the intensity of the active stresses. Therefore, it is necessary to seek bases or criteria that allow such a judgment to be made.…”

Study on milling strategies influence on the quality characteristics in case of composite material

“…There are airplanes that contain over 50% of components made of composite materials, due to the ratio between their weight and their strength. This ratio was also analysed by some researchers using finite element analysis method [1]. Also, these materials are used in formula one [2] with very good results.…”
