Comparison of critical strain energy release rate and fracture energy for timber mode II failure

Journal of Wood Science
This study compares two approaches for evaluating mode II fracture properties in Japanese larch: the critical strain energy release rate (G c) based on linear elastic fracture mechanics and the fracture energy (G f) from non-linear fracture mechanics ...

Fast Buckling Analysis of Stiffened Composite Structures for Preliminary Aerospace Design

Aerospace
Predicting buckling in large-scale composite structures is hindered by the need for highly detailed Finite Element (FE) models, which are computationally expensive and impractical for early-stage design iterations.

Study on Long-Term Stability of Lined Rock Cavern for Compressed Air Energy Storage

Energies
A rock mass is mainly subjected to a high internal pressure load in the lined rock cavern (LRC) for compressed air energy storage (CAES). However, under the action of long-term cyclic loading and unloading, the mechanical properties of a rock mass will ...

Deflection Analysis of Steel Truss Web–Concrete Composite Beams Based on Zigzag Beam Theory

Buildings
To address the inherent inaccuracies of the classical beam theory (which overestimates the flexural stiffness) and the “quasi-plane section method” (which neglects the shear deformation) in the deflection analysis of steel truss web–concrete composite ...
