Robust topology optimization of thin plate structure under concentrated load with uncertain load position

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
This study investigates the robust topology optimization of a thin plate structure under a concentrated load with load position uncertainty. The effect of uncertain load direction, load magnitude, and load distribution in topology optimization problems ...

Nonintrusive coupling of 3D and 2D laminated composite models based on finite element 3D recovery

, 2014
In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate ...

A Cluster Mean Approach for Topology Optimization of Natural Frequencies and Bandgaps With Simple/Multiple Eigenfrequencies

International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.
ABSTRACT This study presents a novel approach utilizing cluster means to address the non‐differentiability issue arising from multiple eigenvalues in eigenfrequency and bandgap optimization. This study builds upon the method proposed by Zhang et al., extending it to eigenfrequency topology optimization using bound formulations.

Bisector and zero-macrospin co-rotational systems for shell elements [PDF]

, 2015
A principal issue in any co-rotational approach for large displacement analysis of plates and shells is associated with the specific choice of the local reference system in relation to the current deformed element configuration.
