INTERACTIVITY IN EARLY-STAGE DESIGN BY REAL-TIME UPDATE OF STRESS INFORMATION FOR EVOLVING GEOMETRIES
DS 68-10: Proceedings of the 18th International Conference on Engineering Design (ICED 11), Impacting Society through Engineering Design, Vol. 10: Design Methods and Tools pt. 2, Lyngby/Copenhagen, Denmark, 15.-19.08.2011
A methodology is introduced for the analysis of small problems of elasticity in which the stress solutions, displayed in conventional contour form, are updated in real time as the engineer deforms the geometry of the object under analysis. The underlying mathematical technique is the Boundary Element Method, and we show how the method can be adapted for continuous update of stress solutions as the geometry evolves. Two performance enhancement strategies are presented, and an illustrative example shows a typical usage of the software tools produced during this project.
