Efficient multi-objective CMA-ES algorithm assisted by knowledge-extraction-based variable-fidelity surrogate model

Zengcong LI et al.

Summary: To accelerate multi-objective optimization for expensive engineering cases, this study presents a KE-VFS-CMA-ES model which is based on knowledge extraction and variable-fidelity surrogate-assisted covariance matrix adaptation evolution strategy. In the first part, the KE-VFS model is established by using a low-fidelity surrogate model to obtain low-fidelity non-dominated solutions, extracting knowledge using the K-means clustering algorithm and space-filling strategy, and combining high-fidelity and low-fidelity sample points. In the second part, a novel model management based on the MHVI criterion and pre-screening strategy is proposed. The results demonstrate the excellent efficiency, robustness, and applicability of KE-VFS-CMA-ES compared to other multi-objective optimization algorithms.

Data-driven non-intrusive shape-topology optimization framework for curved shells

Kuo Tian et al.

Summary: This paper proposes an easy-to-implement data-driven non-intrusive shape-topology optimization framework for curved shells, which includes an offline step and an online step. In the offline step, Latin hypercube sampling is used to generate input data, and a shape equation-driven mesh deformation method is used to obtain the skin shape of the curved shell. In each design domain determined by different skin shapes, topology optimizations are performed, and the results are collected in the output dataset. In the online step, single-loop data-driven optimization is carried out using covariance matrix adaptive evolution strategy and adaptive optimization updating method for efficient optimization results.

Shakedown analysis of bounded kinematic hardening engineering structures under complex cyclic loads: Theoretical aspects and a direct approach

Heng Peng et al.

Summary: This paper introduces two basic formulations of the static shakedown theorem for bounded kinematic hardening models and discusses their equivalence, loading-path-independence conditions, and application to safety margins of engineering structures. A direct approach is proposed to analyze shakedown of KH structures, considering multiple load influences and ensuring high computational efficiency. The approach has been implemented into the Abaqus software platform, serving as a general tool for large-scale shakedown problems in engineering structures with complex geometry and loading conditions.

Overview of reusable space systems with a look to technology aspects

Paolo Baiocco

Summary: Rocket reusability has been studied since the beginning of the space age. While full reusable vehicles are not yet operational, partially reusable launch vehicles have already been flown. Europe's focus on reusing unwinged booster stages or only the orbited spacecraft has become a preferred strategy in recent years.

Shakedown analysis and its application in pavement and railway engineering

Juan Wang et al.

Summary: This paper presents a review of shakedown analysis methods for pavement and railway engineering, introduces new lower-bound and upper-bound methods, and compares the influences of key factors on shakedown limits. It also proposes a unified shakedown limit equation for pavements and railways under repeated moving surface loads.

Design of an innovative laser-assisted four-point bending forming process for high-stiffened structure of aluminum alloy

Jun Guo et al.

Summary: The study proposed the use of laser-assisted four-point bending to form high-stiffened structures of aluminum alloy, finding that the increase in plastic strain was mainly attributed to the elastic strain of the laser scanned area and the bullying effect of adjacent areas. It was demonstrated through simulation and experiment that LAFPB can reduce mechanical force and springback by converting elastic strain energy into plastic strain energy inside the part, leading to improved forming quality.

A comparative study of shape imperfection and internal pressure effects on plastic, shakedown and elastic limit loads using large and small strain formulation of 90° pipe bends

S. Balakrishnan et al.

Summary: This study quantifies the effect of ovality and wall thinning on the plastic, shakedown, and elastic limit loads of pipe bends under cyclic in-plane bending load and internal pressure. The results show that ovality has a significant effect on the limit loads, while thinning has a remarkable effect on the elastic and shakedown limit loads. Mathematical equations were formulated to express the generated limit moment boundaries for shape imperfect pipe bends.
