Is the Free Energy of Hydrogel the Sum of Elastic Energy and Ionic Energy?
, 2006 Introduction Ionised porousmedia are profusely present in biology as well as in geology. Numerical techniques have been developed to handle these materials. The constitutive laws used in these models are satisfactory in relatively stiff materials, such as bone, shale or cartilage. But for high deformable materials (E < 1MPa) they don’t satisfy, both in

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Elastic theory of nanomaterials based on surface-energy density
, 2014 Recent investigations into surface-energy density of nanomaterials lead to a ripe chance to propose, within the framework of continuum mechanics, a new theory for nanomaterials based on surface-energy density.

Moisture damage evaluation using energy based responses
Journal of Civil Engineering and Management, 2017 Monotonic Indirect Tensile tests were performed on asphalt concrete mixtures made of two different types of aggregates. Since the environmental condition is a determining factor in propagation of moisture damage, the effects of temperature and aging were

Multi–layer graphene folds supported on a substrate: a variational model
Materials Research Express, 2020 A mathematical model is developed to study the folding behaviour of multi–layer graphene sheets supported on a substrate. The conformation of the fold is determined from variational considerations based on two energies, namely the graphene elastic energy

Weak elastic energy of irregular curves
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023 A weak notion of elastic energy for (not necessarily regular) rectifiable curves in any space dimension is proposed. Our p -energy is defined through a relaxation process, where a suitable

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
