چکیده

This paper presents a numerical modelling methodology to investigate the thermo-mechanics of carbon reinforced thermoplastic-based laminates in situation mechanical loading combined thermal gradients. It concerns particular case irradiation on one face laminate, where temperature varies both from point laminate and through time, ranges ambient matrix decomposition onset. Temperature is key variable determine physical state properties each phase composite. Particular attention therefore paid identifying respective material according temperature. The developed model based an explicit representation yarn-matrix spatial arrangement within representative volume element considered laminate. From this influence heterogeneous degradation macro-scale dependent composite discussed. Such requires consideration wide range phenomena (modification properties) comprehensive set boundary conditions (heterogeneous distribution heat flux density sample surface, convection, radiation). proposed provides very good prediction laminate’s stiffness evolution up onset further enables analyze gradual efforts take between plies when constant exposure.

Fatigue Life Assessment of Composite Airplane Wing Subjected to Variable Mechanical and Thermal Loads

The purpose of this paper is to estimate the fatigue life of an airplane wing with laminated composite skin, subjected to variable mechanical and thermal loads. To achieve this aim,at first, the three-dimensional model of airplane wing was drawn in CATIA software. Then, by transferring the model to the ABAQUS software, the finite element model of the wing wascreated. H...
