Abstract

Impact responses of welded aluminium plates made from AA6061-T6 are investigated experimentally and numerically, focusing on the HAZ softening phenomenon. Specimens with different weld numbers and impact positions are designed to study the softening effect on damage characteristics. Material tests, including hardness and tensile testing, are carried out to provide necessary numerical input data for the material surrounding the weld. Finite element simulations of the impact tests are performed with detailed modelling of softening zones around the welds, analysing the damage characteristics of specimens under different impact cases. Finally, standard simplified modelling methods for softening zones are compared to systematically evaluate the effectiveness of numerical modelling techniques in welded aluminium plates under impact loads.
