Seepage Damage Statistical Model of Filled Fractured Rock considering Structural Surface and Failure Characteristic

Advances in Civil Engineering, 2021
Damage theory studies the whole process of initiation, propagation, and instability of microcracks in materials and provides an important basis for the estimation of the risk of materials.

Breakdown of disordered media by surface loads

, 2004
We model an interface layer connecting two parts of a solid body by N parallel elastic springs connecting two rigid blocks. We load the system by a shear force acting on the top side.

Micromechanical response of fibre-reinforced materials using the boundary element technique [PDF]

, 2003
The Boundary Element Method (BEM) and the Embedded Cell Approach (ECA) have been used to analyse the effects of constituent material properties and fibre spatial distribution on the localised behaviour of a transversely loaded, unidirectional fibre ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Failure Probabilities and Tough-Brittle Crossover of Heterogeneous Materials with Continuous Disorder

, 1998
The failure probabilities or the strength distributions of heterogeneous 1D systems with continuous local strength distribution and local load sharing have been studied using a simple, exact, recursive method.

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
