Metalforming
Micro-Meso-Macro Tube Hydroforming
We seek to study the fundamental mechanics of hydroforming process to enable micro and macro hydroforming of complex shapes by considering THF as as system. We seek to explore innovative non-conventional loading path for THF as well as developing THF optimization schemes which include variables for enhancing tribological performance.
Real–Time Loading Path for THF Using Multidimensional Cubic-Spline Interpolation
We have conceived an innovative technique for developing an interactive, real-time database that would be able to predict loading paths for many THF components and hence reduce the computational time required. By classifying most of the commercial THF parts into families, parameters such as material properties, part geometry, and tribological factors were simulated by category and stored in the database. Multidimensional cubic spline interpolation was implemented to enable an end user to request from the database a loading path for a wide range of conditions.
IMPACT:
- Multidimensional cubic spline interpolation allows the database to output the required loading path in less than 1 second
- Eliminate the need for running multiple FEA simulations for similar parts.
