Smart soft materials have gained increasing attention in recent years because of their adaptive behaviors to external multi-physics stimuli, enabling diverse applications across multiple fields. Here, we show programmable wrinkling morphological patterns on liquid crystal network (LCN) bilayers bonded to compliant substrates under thermal load, by tuning the orientation of directors between LCN bilayers. We propose a solid-shell formulation that merges enhanced and natural assumed strain approaches to investigate the pattern formation and morphological transition of LCN bilayers.

Liquid crystal elastomers (LCEs), as a unique class of smart soft materials combining the properties of liquid crystals and hyperelasticity, are capable of rapid, anisotropic, and reversible deformations in response to mechanical, thermal or optical stimuli. Here, we report a hitherto unknown stretching-induced twisting behavior of LCE bilayer strips. Under uniaxial stretching, we reveal that due to the spontaneous mismatch strain arising from interlayer anisotropy, the bilayer strips exhibit notable twisting deformations.

Title: Uncertainty Quantification and Generative Modeling Using Multi-fidelity Strategies

The Computational Mechanics and Methods (CM3) Group in the Department of Mechanical and Aerospace Engineering at the University of Kentucky is seeking highly self-motivated individuals who have great interest in the broad research areas of computational solid mechanics and methods, beginning Fall 2025. Interested individuals should send a detailed CV and official transcripts to Dr.

Dear iMechanicians,

Let me bring to your attention the IUTAM Symposium on Chemo-Mechanics that we are organising this summer in Oxford. We have an excellent cohort of speakers covering a wide range of chemo-mechanics topics (hydrogen embrittlement, battery degradation, corrosion/oxidation, hydrogels, etc.). In addition to invited talks, there will be opportunities to contribute with posters. You can find all the information here: https://chemomechanics.web.ox.ac.uk/

Call for Abstracts
We invite submissions for Topic 1-1: Mechanical Metamaterials at ASME IMECE 2025, to be held in Memphis, Tennessee.

We currently have one postdoctoral research position available in the Injury Biomechanics Laboratory at Robert Morris University in Pittsburgh, PA. This position involves the development of high-fidelity finite element head models and the design of computational studies to advance our understanding of blast-induced traumatic brain injury (TBI).  A Ph.D. in mechanical engineering, biomedical engineering, mechanics, or related field is required.

I am looking for an enthusiastic Student or Postdoc who would like to enhance his/her knowledge in the field of Computational Mechanics. The focus in this three-year research project is about Modular peristaltic surface conveyor with AI based digital twin for polybags and includes the simulation of elastomer membranes by using Isogeometric Analysis and AI generated material models. The deadline for application is the 6th of February. 

We are now accepting applications for the fully-funded PhD position (applicable worldwide) on Computational Methods for Fluid-Structure Interaction problems.
