A performance-based early design must assess the life cycle performance of a sizable
design space at low computational cost and limited data. This paper evaluates the relative …

Despite advances in computer capacity, the enormous computational cost of running
complex engineering simulations makes it impractical to rely exclusively on simulation for …

In this paper, the direct differentiation of generalized-α time integration is derived, equations
are introduced and results are shown. Although generalized-α time integration has found …

Reducing the weight of a system leads to lower forces being exerted, which in turn allows for
lower requirements and an even lighter system. This “virtuous circle of lightweight …

In this paper, for efficiently reducing the computational cost of the model updating during the
optimization process of damage detection, the structural response is evaluated using …

Generally, updating a finite element model can be considered as an optimization problem
where its physical parameters may be adjusted such that analytically computed features …

In this paper, a multi-objective optimization strategy for efficient design of turbomachinery
blades using sparse active subspaces is implemented for a turbofan stage design. The …

Surrogate-based Optimization is a useful approach when the objective function is
computationally expensive to evaluate, compared to Simulation-based Optimization. In the …

Surrogate model has received increasing attention for use in detecting damage of structures
based on vibration modal parameters. However, uncertainties existing in the measured …

Although current advanced generative models exhibit strong adherence to complex textual
descriptions, industrial applications often require numerical conditions for the target object …
