Physics-informed neural networks for transient diffusion interface problems: Kolmogorov–Arnold networks versus multilayer perceptrons

Submitted by vrh59ir on
research
Physics-informed neural networks (PINNs) remain challenging for transient interface problems with discontinuous coefficients, sharp interfacial gradients, and multiple temporal scales. In this work, we develop a PINN framework for transient diffusion interface problems with physically consistent interface conditions and compare multilayer perceptron (MLP) architectures with several radial-basis-function Kolmogorov–Arnold network (RBF–KAN) variants.

Maxwell, Airy and Hill walk into a bar, here is the theorem they write

Submitted by hnassar@uh.edu on
research

The lemma of Hill (or of Hill-Mandel) is crucial to the consistent treatment of effective properties in the theory of composites. Building on various classical results (notably by Maxwell and Airy), I've recently applied the lemma sort of "out of context" to characterize (count really) the (infinitesimal) isometric deformations of periodic surfaces.

Postdoctoral fellowship in the area of crystal plasticity finite element modeling

Submitted by HamidAbdolvand on

Applications are invited for a 2-year postdoc position in the area of crystal plasticity finite element modeling of polycrystals. This is a full-time position at the University of Western Ontario, Canada, and the selected applicant may begin immediately. In addition, this position is extendable for another two years, depending on the availability of funds and the applicant’s performance.

Multi-objective topology optimization of heat pipe cooled reactor core subjected to thermo-mechanical loadings

Submitted by Jinxiong Zhou on

The Heat Pipe Cooled Reactor (HPR) is a critical component for mobile energy supply in extreme environments, such as deep space exploration, deep-sea submersion, and remote engineering operations, where lightweight design is a key performance indicator. Existing studies primarily focus on the layout and sizing of the heat pipes, while the matrix, which serves as both the primary heat transfer medium and the load-bearing structure, constitutes a significant portion of the mass but has not been adequately explored.

Modeling viscoelasticity-viscoplasticity of high-strain composites for space deployable structures

Submitted by Jinxiong Zhou on
Space deployable structures made of thin-ply fiber-reinforced composite laminates exhibit significant time-dependent mechanical behaviors, including stress relaxation, shape recovery, and permanent residual deformation throughout their service period. Currently, there is a lack of an appropriate composite laminate model that is able to fully describe these phenomena.
