Evolutionary topology optimization for elastoplastic structures via isogeometric analysis

Engineering Optimization, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 27

Published: Jan. 3, 2025

In this article, an evolutionary isogeometric topology optimization method for elastoplastic materials while minimizing compliance is proposed. The material and constitutive models are grounded in the framework of finite strain nonlinear isotropic hardened plasticity, yield surfaces undergo updates through explicit numerical scheme elastic prediction/plasticity correction. application analysis intended to meet requirements high-order continuity between adjacent elements during transitional states. For evolutionary-based optimization, adjoint sensitivity expressions developed under displacement-loaded control, realization performed. Numerical results demonstrate that proposed performs well with different effective scenarios various specifications. comparison element shows technique yields fast yet accurate solutions.

SyMO: A Hybrid Approach for Multi‐Objective Optimization of Crystal Growth Processes

Advanced Theory and Simulations, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 28, 2025

Abstract Crystal growth, particularly silicon, is pivotal in the semiconductor industry. It serves as foundation for electronic devices, solar cells, and various advanced technologies. The Czochralski method a prominent technique producing large single silicon crystals, well‐known its complexity due to precise control required over temperature gradients, interface dynamics, impurity incorporation— all critical factors growing uniform, high‐quality crystals. This paper proposes hybrid SyMO (Symbolic regression Multi‐objective Optimization) framework that combines Computational Fluid Dynamics (CFD), machine learning, mathematical optimization techniques investigate effects of process parameters, furnace geometries, radiation shield material properties on key crystal quality metrics. data set created from axisymmetric CFD simulations used fit symbolic models effectively capture complex nonlinear relationships, ensuring accurate deflection ratio predictions. SR equations are integrated into multi‐objective model simultaneously optimizes efficiency. obtained results validated through additional confirm accuracy solution. demonstrated successfully generalizes dependencies across parameters provides robust, solutions.
