NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

Closed‐Form Hypoplastic Solutions for Normally Consolidated Soil in Element Tests

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The hypoplastic theory has gained significant attraction in the geomechanics community for constitutive modeling and numerical simulation. However, the absence of an analytical benchmark for numerical simulations incorporating the hypoplastic model remains a notable gap. This study revisits the basic hypoplastic model for normally consolidated

Numerical Modelling of Frictional Sliding Induced Damage and Heating Effects on Rock With an Application to Sievers’ J‐Miniature Drilling on Granite

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The present study develops a finite element‐based numerical method for simulation of frictional rotational sliding induced damage and heating effects on rock. The method is applied to the Sievers’ J‐ miniature drill test, which is widely used for estimating the rock drillability and predicting the cutter life.

Comparative Insights Into the Structural, Electronic, Elastic, Vibrational, and Optical Properties of Rare‐Earth Palladium Borides RBPd3 (R = Lu, Yb)

open access: yesNano Select, EarlyView.
This study focuses on the ground‐state properties of two rare earth palladium borides, LuBPd3 and YbBPd3. The WIEN2k package is used to investigate the properties. The compounds’ exceptional thermal and optoelectronic properties make them suitable for high‐temperature applications, UV absorbers, and infrared (IR) shielding materials.
