An efficient approach for reliability-based topology optimization

Engineering Optimization, 2015
This article presents an efficient approach for reliability-based topology optimization (RBTO) in which the computational effort involved in solving the RBTO problem is equivalent to that of solving a deterministic topology optimization (DTO) problem. The methodology presented is built upon the bidirectional evolutionary structural optimization (BESO ...

Reliability-Based Topology Optimization of Laser Scanned Model

10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004
Recent engineering process requires fast development and manufacturing of the products. This paper mainly discusses the process of rapid product development (RPD) from the reverse engineering to the optimal design. A laser scanning system scans a product and the efficient data processing method reduces the scanned point data.

A new design for the humerus fixation plate using a novel reliability-based topology optimization approach to mitigate the stress shielding effect.

Clinical Biomechanics, 2022
BACKGROUND Due to high stiffness, metal fixation plates are prone to stress shielding of the peri-prosthetic bones, leading to bone loss. Therefore, it has become important to design implants with reduced rigidity but increased load-carrying capacity ...
