Deep Underground Science and Engineering, Volume 5, Issue 2, Page 426-445, June 2026.The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

High strain rate tensile testing of sheet materials using three Hopkinson pressure bars
EPJ Web of Conferences, 2012 In an attempt to circumvent the inherent problems associated with Split Hopkinson Tensile Bar (SHTB) systems, a new experimental technique is proposed for the high strain rate tensile testing of sheet specimens in Split Hopkinson Pressure Bar (SHPB ...

Exploration, Volume 6, Issue 3, June 2026.Developing strong and sustainable materials is essential for reducing reliance on metals and lowering carbon emissions. Inspired by how plants naturally harden their cell walls, we created a rapid process that transforms bamboo into an ultra‐hard structural material by rebuilding lignin‐like networks within its structure.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Triply periodic minimal surfaces (TPMS) constitute a prominent class of cellular structures and have gained considerable attention in current research. These structures are genus‐infinite surfaces with zero mean curvature, which prevents self‐intersection. They also exhibit periodicity in all three spatial directions and exhibit enhanced multi‐

Feasibility of Two-Dimensional Numerical Analysis of the Split-Hopkinson Pressure Bar System
, 1974 The feasibility of two-dimensional numerical analysis of the split-Hopkinson pressure bar experiment is proven. A general elastic-plastic artificial viscosity computer program is shown to give an adequate solution for two-dimensional elastic response of ...

Small Methods, Volume 10, Issue 11, 8 June 2026.The performance of polymer blend semiconductors is governed by both the degree of phase separation and crystallization, but these two aspects have remained unresolved. We report methods for mapping amorphous‐amorphous as well as amorphous‐crystalline phase separation in polyfluorene‐based polymer blends using spatially resolved nanobeam electron total ...

Study of adiabatic localized shear in metals by split Hopkinson pressure bar method
EPJ Web of Conferences, 2011 This paper is devoted to the technique for study of localized shear using hat-shaped samples by the split Hopkinson pressure bar (SHPB) method. Also it is devoted to results obtained in tests with samples of copper M1 and steel 09G2S.

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.Abstract Variations in the elemental C:N:P ratios of organic matter (OM) influence the coupling of carbon and nutrient cycles in the ocean. In this study, we assess the relevance of OM C:N:P stoichiometry for regional carbon cycling in the northwest European shelf seas (NWES).
