| Popis: | Since its development, FSW has been pointed as an excellent alternative to fusion welding. Although this technology was initially settled for welding aluminum alloys, recent developments allowed extending its application to a more diversified range of base materials. Due to the complexity of the process, the use of numerical simulation become a common practice for optimizing process parameters and/or for understanding the physical phenomena governing it, which are impossible to be analyzed using common experimental practices. In present work, COMET software was used to model different conceptual materials, designed in order to enable a deep analysis of the influence of base materials plastic properties, at different temperatures and strain rates, on heat generation and tool torque. Materials with different plastic behavior were tested using Norton-Hoff constitutive model. Torque and temperature were evaluated and related to base materials mechanical properties. Numerical results are compared and discussed. |
