Damage characteristic of split-re-closed shale under impact shearing

International Journal of Coal Science & Technology
This study proposes methane in-situ explosive fracturing (MIEF) for reactivating closed fractures in aging shale gas reservoirs. Employing a split Hopkinson pressure bar (SHPB) system, this study investigates the impact-shearing damage characteristics of

3D Numerical Solution for Natural Fracture Distribution in Tight-Sand Reservoirs Based on Damage Mechanics with Sets of 2D Seismic Data

Applied Sciences
Natural fracture development in tight-sand gas reservoirs is strongly controlled by tectonic evolution yet remains difficult to characterize using conventional seismic interpretation due to limited resolution. This study presents a damage-mechanics-based

Continuum Damage and Scaling of Fracture [PDF]

, 2001
This paper presents a simple application of continuum damage modelling to failure analysis. An isotropic damage model is described and its non local enhancement discussed. The calibration of the model parameters is addressed with the help of structural size effect data.

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.
