Sažetak
The multi-material concept in design using lightweight components (e.g. light metals and cellular materials) provides for several advantages in various industries with the aim to develop cost-effective energy absorbing lightweight structures with reliable and predictable mechanical behaviour. This approach allows designing and manufacturing highly efficient structures with lower mass in comparison to the traditional designs based on solid materials. In this study thin-walled aluminium alloy tubes filled with different porous fillers have been characterized based on the three-point bending tests. Four porous filler types have been considered herein: i) closed-cell foam, (ii) advanced pore morphology (APM) foam, (iii) hybrid APM foam, and (iv) metallic hollow sphere structure (MHSS). Their bending response has been evaluated at different loading velocities and compared to the behaviour of the empty thin-walled tube. In order to follow the deformation mechanics infrared thermography has been used to capture the plastification zones at dynamic loading regimes. Additionally, the interaction between the porous filler and the inner tube wall has been evaluated. The results provide comprehensive description of the mechanical behaviour with detailed bending properties, including the strain energy absorption capabilities, of tubes filled with four different types of cellular material.
