Stiff and Deformable Quasicrystalline Architected Materials
Matheus I. N. Rosa, Konstantinos Karapiperis, Kaoutar Radi +1
Architected materials achieve unique mechanical properties through precisely engineered microstructures that minimize material usage. However, a key challenge of low-density materi…
On a -Structure in Geometrically Linearized Elasticity: Qualitative and Quantitative Analysis and Numerical Simulations
Roman Indergand, Dennis Kochmann, Angkana Rüland +2
We study the rigidity properties of the -structure for the symmetrized gradient from \cite{BFJK94} qualitatively, quantitatively and numerically. More precisely, we complement…
HyperCAN: Hypernetwork-Driven Deep Parameterized Constitutive Models for Metamaterials
Li Zheng, Dennis M. Kochmann, Siddhant Kumar
We introduce HyperCAN, a machine learning framework that utilizes hypernetworks to construct adaptable constitutive artificial neural networks for a wide range of beam-based metama…
Atomistic-informed phase field modeling of magnesium twin growth by disconnections
Yang Hu, Dennis M. Kochmann, Brandon Runnels
The nucleation and propagation of disconnections play an essential role during twin growth. Atomistic methods can reveal such small structural features on twin facets and model the…
A mixed-order quasicontinuum approach for beam-based architected materials with application to fracture
Kevin Kraschewski, Gregory P. Phlipot, Dennis M. Kochmann
Predicting the mechanics of large structural networks, such as beam-based architected materials, requires a multiscale computational strategy that preserves information about the d…
Physics-Informed Diffusion Models
Jan-Hendrik Bastek, WaiChing Sun, Dennis M. Kochmann
Generative models such as denoising diffusion models are quickly advancing their ability to approximate highly complex data distributions. They are also increasingly leveraged in s…
Finite-temperature grain boundary properties from quasistatic atomistics
Miguel Spínola, Shashank Saxena, Prateek Gupta +2
Grain boundary (GB) properties greatly influence the mechanical, electrical, and thermal response of polycrystalline materials. Most computational studies of GB properties at finit…
