Reliability-based topology optimization of trusses with stochastic stiffness [PDF]

open access: yesStructural Safety, 2013
Abstract A new method is proposed for reliability-based topology optimization of truss structures with random geometric imperfections and material variability. Such imperfections and variability, which may result from manufacturing processes, are assumed to be small in relation to the truss dimensions and mean material properties and normally ...

An Investigation of the Recent Developments in Reliability-based Structural Topology Optimization [PDF]

open access: yesPeriodica Polytechnica Civil Engineering, 2023
Optimizing a structure's topology involves finding the best possible distribution of material and connections within a given design space. It has a significant effect on its performance, which is why there has been a meteoric rise in the number of articles published on the topic over the last two decades.
