“…Furthermore, a multitude of recent studies have delved into various applications involving BESO, including the integration of LSM with BESO [105], the implementation of BESO with cast constraints [55], and BESO with Additive Manufacturing constraints [106,107,108]. Exploration of multi-scale optimisation with BESO has been undertaken [109,110,111], along with investigations into buckling in TO [112], considerations of fatigue in design [113], analyses of nonlinear structures under dynamic loads [114], examinations of nonlinear reliability in TO [115], exploration of crash-worthiness in TO using BESO [116], and optimisation of frequency [117,118].…”

Satellite launches are critical amid increasing demands for advanced services. Rising costs urge innovation in engineering. Enhancing satellite structural integrity during launches is crucial due to intense vibrations. Topology optimisation and additive manufacturing converge as promising solutions. Topology optimisation uses mathematical techniques to iteratively improve structures by reducing mass while enhancing attributes like load capacity. This field, active for about three decades, employs continuum and discrete algorithms to optimise structures. Recent trends show optimised structures through topology optimisation and additive manufacturing promise cost-effective and high-performance solutions. This study aims to extensively review topology optimisation methods, specifically focusing on satellite structures, to shape future developments within the years to come.

“…However, a topology optimization problem is often tuned for a single loading condition. While there are works that adapt topology optimization to multiple loading conditions, they can become computationally intense [54,55]. Instead, this work mainly focuses on smooth and fast phase transitions that can find applications in conceptual design stages.…”
