Metallic Additive Manufacturing Process Simulations
内蒙古11选五走势图 www.ooc4.com Additive Manufacturing (AM), widely known as 3D printing, is a manufacturing process where a component is produced, layer by layer, from digital 3D data. AM has developed rapidly in the last 10 years and has demonstrated significant potential in cost reduction of performance-critical components. This can be seen through improved design freedom, reduced material waste, and reduced post-processing steps.
Modeling AM processes not only provides important insight into competing physical phenomena that lead to final material properties and product quality, but also provides the foundation for?qualification of the manufacturing process,?exploiting the design space towards functional products and materials.
The length and timescales required to model AM processes and to predict the final workpiece characteristics are very challenging.?
Models must deal with multiple physical aspects, such as heat transfer and phase changes, as well as the evolution of material properties and residual stresses throughout the build time. Therefore, the modeling task is a multi-scale, multi-physics endeavor calling for a complex interaction of multiple algorithms.
