🔊 Effective-medium models for multi-modal metamaterial panels—now for the real world: finite size, arbitrary BCs & non-uniform resonators. Coupled with Det-SEA for fast diffuse STL; validated vs FEM. Broadband attenuation survives boundary effects. 🔗 https://t.co/R1rYJWgu9A

🔋 Microstructure–chemomechanics in solid-state NMC cathodes: Phase-field (MOOSE) modeling links grain shape/orientation and interfacial toughness to crack initiation/propagation—revealing design knobs to suppress fracture and stabilize performance. 🔗 https://t.co/Jhkq4u2fm1

🧪 What triggers yielding in DN hydrogels? Birefringence shows edge damage zones grow, then merge → yield. Yield stress is intrinsic; narrow samples show pseudo size effects. Define intrinsic crack length cI ≈ 10× mesh size. 🔗 https://t.co/jRBMqgcFK3

🌀 Collective snapping in bumping buckled beams: Spacing D decides which of two unequal beams snaps first; the critical D* scales linearly with total thickness. Explained by a pre-snap pitchfork bifurcation. Experiments + FEM + Bellini-truss model. 🔗 https://t.co/UqfQiI0BHv

🌀 Twist–spacing coupling in vdW bilayers. In reconstructed tBLG, interlayer distance increases ~3.37→3.45 Å as twist goes 0–4°, driven by atomic reconstruction. Similar behavior in MoS₂, MoSe₂, WS₂, WSe₂—enabling co-tuning by twist & spacing. 🔗 https://t.co/58ebRmoix7

🔋 3D multi-particle finite element method (MPFEM) for Li-ion electrodes: a mesoscale model that captures particle packing, matches compression experiments, and reveals factor effects—guiding safer, more reliable LIB design. 🔗 https://t.co/eoo4ooBuEC

🪢 Tying CNTs with a trefoil knot (double-helix lasso)! MD shows tightening/release mechanics across diameters; helical H reorientation prevents untying. Knot curvature ↔ persistence quantified—guiding bottom-up design of nanocomposites. 🔗 https://t.co/3PfpGpnA18

📟 FEM of curved-array flexible electronics under impact shows: 🔹 Layer order controls transient response 🔹 Planar stacks cushion functional silicon best 🔗 https://t.co/lwoAmBOnpY

🧠⚙️ AI reads cell forces from images. A GAN trained on TFM + phase-field data predicts traction maps, captures collective durotaxis, and even generalizes to other cell types with a single scaling factor. 🔗 https://t.co/xt4jROpK1P

🧨 Fracture isn’t equilibrium. In 2D crystals, cracks follow paths set by unrelaxed edge states—not relaxed structures. A neural network force field (NN-F3) reveals lattice kinks → large-scale crack patterns. 🔗 https://t.co/XgmE78JI6L
