In this research, the maximum stress, Hashin, Puck, LaRC03, and Northwestern University (NU) criteria are analyzed based literature data, analytical results obtained using a MATLAB program numerical from an Abaqus finite-element model. The applicability reliability of these failure for predicting damage in thermoplastic laminates evaluated on results. According to results, stress criterion prov...

Abstract In this paper, a general three-dimensional finite element model composed of eight-node three-dimension cohesive elements and solid with reduced integration for low-velocity impact analysis composite materials is established. Firstly, the continuum damage mechanics applied to simulate initiation evolution intra-laminar damage. Based on zone , are inserted between layers predict inter-la...

The response over the low-velocity impact of various shape impactors on a glass fiber reinforced polymer composite has been numerically analyzed with hemispherical, flat, partially flat and truncated shaped impactor used to analyze behavior resistance GFRP at speeds. numerical analysis was carried out using finite element software, ABAQUS (Dynamic/Explicit). To assess laminates while impacting,...

The blades of wind turbines placed in cold climate regions are exposed to the risk icing phenomena which impact their lifetimes. This paper proposes a numerical model simulate 50 mm ice thickness localized on tip side horizontal turbine blade, and study its mechanical behavior. blade wasmodeled with finite element method (FEM)in ABAQUS software taking into account aerodynamic, centrifugal inert...

The purpose of this work aims to assess the failure an open-hole composite laminate subjected tensile loading, using different progressive damage approaches. Within Abaqus, a user-defined material subroutine (UMAT) was developed and implemented by applying combination Puck’s criterion gradual degradation model. In addition, integrated model in Abaqus based on Hashin criteria coupled with contin...

We address the attainability of the Hashin-Shtrikman bounds for multiphase composite materials. We demonstrate that the Hashin-Shtrikman bounds are not always attainable and give new restrictions on the attainable Hashin-Shtrikman bounds in terms of the conductivities and volume fractions of the constituent phases. New optimal microstructures are also constructed to attain the Hashin-Shtrikman ...
