Predicting deformation mechanisms in architected metamaterials using GNN
Padmeya Prashant Indurkar, Sri Karlapati, Angkur Jyoti Dipanka Shaikeea +1
The present paradigm in design and modelling of lattice architected mechanical metamaterials is mostly limited to traditional numerical methods like finite element analysis. Recent…
Mechanical metamaterials: does toughness characterize fracture?
Angkur Jyoti Dipanka Shaikeea, Huachen Cui, Mark R. O'Masta +3
Rapid progress in additive manufacturing methods has created a new class of ultralight and strong architected metamaterials that resemble periodic truss structures. The mechanical…
The influence of strut waviness on the tensile response of lattice materials
P. E. Seiler, K. Li, V. S. Deshpande +1
Recent advances in additive manufacturing methods make it possible, for the first time, to manufacture complex micro-architectured solids that achieve desired stress versus strain…
Regulation of notch sensitivity of lattice materials by strut topology
K. Li, P. E. Seiler, V. S. Deshpande +1
We propose a local reinforcement technique for lattices in the vicinity of a stress-raiser such as a notch, in order to elevate the macroscopic strength and ductility. A spatially…
Nanofibril-mediated Fracture Resistance of Bone
Ottman A. Tertuliano, Bryce W. Edwards, Lucas R. Meza +2
Natural hard composites like human bone possess a combination of strength and toughness that exceeds that of their constituents and of many engineered composites. This augmentation…
An assessment of the J-integral test for a metallic foam
H. C. Tankasala, T. Li, P. E. Seiler +2
An assessment is made of the J-integral test procedure for initial crack growth in an open-cell aluminium alloy foam by combining finite element (FE) simulations with experiment. I…
