Dynamic modelling strategy of a shaft-disk-blade coupling system integrating beam and shell theories
Despite the remarkable success achieved in modelling the rotor-disk-blade coupling system, the existing research does not adequately consider both the structural flexibility and the rotating effects in the sha...

A new radial basis function active learning method based on distance constraint for structural reliability analysis
Strongly nonlinear structural systems exhibit high computational errors when dependability is calculated using conventional approaches such as the primary second-order method of moments and the secondary secon...

Polygonal multiresolution topology optimization of multi-material structures subjected to dynamic loads
Topology optimization of multi-material structures under dynamic loads is implemented to minimizing compliance on polygonal finite element meshes with multiple volume constraints. A multiresolution scheme is i...

Modeling the temperature-dependent Young’s modulus of short fiber reinforced metal matrix composites and its particle hybrid composites
Knowledge of the temperature-dependent Young’s modulus (TDYM) is fundamentally important for it is a key index to access the deformation-resisting ability over a wide temperature range. In this article, consid...

A rigid body dynamics simulation enhanced representative volume element builder for CNT/Al composite
A novel representative volume element (RVE) builder is developed to solve the strong “framing effect” problem in previous RVE builders. Taking advantage of rigid body dynamics simulation, the new RVE builder c...

A topology optimization method for hyperelastic porous structures subject to large deformation
Porous infill, rather than the solids, can provide high stiffness-to-weight ratio, energy absorption, thermal insulation, and many other outstanding properties. However, porous structure design to date have be...

Mesoscale analysis of rubber particle effect on young’s modulus and creep behaviour of crumb rubber concrete
This paper presents a mesoscale model to investigate the rubber particle effect on the mechanical properties of crumb rubber concrete (CRC). Taking Young’s modulus as an example, the short-term and long-term c...

Deformation-based accurate geometric model of stranded wire helical spring
As a kind of cylindrical spring structured with a helically wound strand, the stranded wire helical springs are widely employed as reset components in engineering fields. The accurate description of the spring...
