| Abstract [eng] |
Engineering components undergo structural failure in their lifetime due to repetitive loads and therefore cause imbalance in their assembly and compromise their further process. Hence identifying the failure prone areas and pre-dicting the failure modes are of significant importance in or-der to reduce the risk of damage and improve their working lifetime. An experimental approach was implemented and the data was attempted against finite element method-based numerical simulations. An experimental procedure was car-ried out on D16T Al-alloy specimens to study their mechan-ical behaviour and to determine their physical characteris-tics. The mechanical properties obtained from the experi-mental study are then attempted against apparent finite ele-ment modelling techniques and the material's constitutive behaviour are presented for the tension, torsion and com-bined tension-torsion loads. The various stress-strain state results of the simulations were used in determining the fa-tigue predictions and the influence of the presence of holes in the engineering components are demonstrated. |
