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.
Dear colleagues,
I am pleased to invite you to the next webinar in the Extreme Mechanics Letters (EML) Webinar Series.

"Disentangling Uncertainty in AI for Engineering"
Date: Wednesday, 15 July 2026
Time: 10:00 am Boston / 3:00 pm London / 4:00 pm Paris / 10:00 pm Beijing
The International Society of Materials Modeling (ISMM) is pleased to announce the call for nominations for the 2026 ISMM Awards and Honors.
Nominations are now open for:
1) Distinguished Career Achievement Award in Materials Modeling: Recognizing outstanding, sustained contributions to materials modeling over a distinguished career.
Past recipients:

I am hiring a postdoc at the University of Oxford to work on my ERC Starting Grant ResistHfracture project. Further details below and at:

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.
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.
The Advanced Interface Design for Extremes (AIDE) Laboratory, led by Dr. Kasra Momeni, invites applications for a one-year Postdoctoral Research Associate position in computational materials science. The anticipated start date is Fall 2026 or January 2027, depending on the candidate's availability.
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:
