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.

finite elements

I wrote a Windows tool for postprocessing finite-element results: figures, animations, and reproducible scenes from EnSight Gold, VTK, ParaView, and STL files.

Everything it draws is vector-based — contours, Gouraud shading, PDF export included. No bitmaps on sight.

Multi-step transient analyses, tensor fields, and symmetry replication are supported.

Free, self-contained, documented:

Submitted by info@signatur.dk on
job
Denmark

The Department of Food Science, Aarhus University, invites applications for a two-year postdoc position in plant physiology and molecular biology of EV-based plant-microbe communication. The position is part of the EU-funded EVOLVE project and focuses on controlled-environment biological testing of extracellular vesicles as a non-GMO platform for steering plant performance and plant-microbe interactions.

Expected start date and duration of employment

This is a two-year fixed-term postdoc position from 1 November 2026 or as soon as possible thereafter.

A new perspective in linear Cauchy Elasticity: variational minimum principles for statics, dynamics, and heterogeneous materials

Submitted by Amit Acharya on
research

A variational minimum principle for linear elastodynamics of a possibly heterogeneous material without a stored energy function is developed. It involves a change of variables to dual fields, and results in a degenerate elliptic Euler-Lagrange system, even when the primal elastodynamics is hyperbolic. Uniqueness assertions for the dual dynamic and static problems and implications of the degenerate ellipticity are sketched. Some implications pertaining to heterogeneous materials and ones with indefinite elastic moduli are discussed.
