Reliability-Based Topology Optimization with a Proportional Topology for Reliability

Aerospace
This research proposes an efficient technique for reliability-based topology optimization (RBTO), which deals with uncertainty and employs proportional topology optimization (PTO) to achieve the optimal reliability structure. The recent technique, called

Proportional Topology Optimization under ‎Reliability-based Constraints [PDF]

Journal of Applied and Computational Mechanics, 2022
Topology optimization is a methodology widely used in the design phase that has gained space in engineering. On the other hand, uncertainty is present in material properties, loads, and boundary conditions in practically any design.

Nonlinearity investigation of reliability-based topology optimization strategies with application to total hip replacement [PDF]

E3S Web of Conferences, 2021
In literature, the topology optimization can be divided into two main models. The first model is called Deterministic Topology Optimization (DTO) producing a single configuration for a given design space.

Reliability based geometrically nonlinear bi-directional evolutionary structural optimization of elasto-plastic material

Scientific Reports, 2022
The aim of this paper is to integrate the reliability-based analysis into topology optimization problems. Consequently, reliability-based topology optimization (RBTO) of geometrically nonlinear elasto-plastic models is presented.
