The utilization of surrogate models to approximate complex systems has recently gained
increased popularity. Because of their capability to deal with black-box problems and lower …

Consider the loss of diversity of the bodies at the later optimization stage and the low
efficiency of the global searching ability of the traditional colliding bodies optimization …

Preform design refers to the intermediate geometric design between the initial tube blank
and the desired product. A proper preform design can improve the formability of the tubular …

A stochastic model updating framework is proposed in this work to address the problem of
uncertain model calibration. This framework includes an effective uncertainty quantification …

Reducing the weight of floor beams is a promising way to carry out the lightweight design of
the rack car body. However, the reduction will generally amplify the vibration of the car body …

The present article aims at performing a global sensitivity analysis of modal properties of a
frequency dependent viscoelastic sandwich plate. The latter are evaluated using a finite …

This paper investigates both the magnitude and distribution of temperature field, residual
stress and deformation of DH36 steel fillet welded T-joints through the numerical simulation …

Abstract Active learning Kriging-based Inverse reliability analyses (AK-IRs) is proposed to
addresses nonlinear and low-probability failure issues in inverse reliability analysis (IRA) …

Since electric multiple units obtain electricity from the catenary through the pantograph, a
good pantograph-catenary contact is essential for ensuring current collection quality for the …
