A mesoscopic theory of damage and fracture in heterogeneous materials

open access: closedTheoretical and Applied Fracture Mechanics, 2004
Abstract Deformation patterns in solids are often characterized by self-similarity at the mesolevel. The framework for the mechanics of heterogeneous solids, deformable over fractal subsets, is briefly outlined. Mechanical quantities with noninteger physical dimensions are considered, i.e., the fractal stress [σ ∗ ] and the fractal strain

Dynamic crack mechanism model place in the designing of the buildings [PDF]

open access: yesMATEC Web of Conferences, 2021
The materials that we use always have some defects. Under static, cycling or dynamic load the materials as a function of the crack size and load environment can initiate a fracture. The crack mechanism depends on several factors, like material properties,

Prediction Method for the Ground Vibration Damage Boundary of Thick and Hard Rock Layer Fracture Type Mine Quakes

open access: yesGeofluids, 2022
In this study, based on the example of the ground vibration damage response of a thick and hard rock layer fracture type mine quake, and by applying the theories of mine pressure, rock mechanics and vibration energy principle, the concept of “vibration ...

Early Detection of Damages Based on Comprehensive Theory of Deformation and Fracture [PDF]

open access: yesThe 18th International Conference on Experimental Mechanics, 2018
Numerical studies have been conducted based on the recently published Deformation Field Theory. Effects of pulling rates on displacement waves and volume expansion waves are analyzed in a finite element model (FEM) of a solid experiencing a uni-axial tensile load.

Effect of fibre arrangement on the multiaxial fatigue of fibrous composites: a micromechanical computational model [PDF]

open access: yesFracture and Structural Integrity, 2015
Structural components made of fibre-reinforced materials are frequently used in engineering applications. Fibre-reinforced composites are multiphase materials, and complex mechanical phenomena take place at limit conditions but also during normal service

Automatic Identification of Critical Damage Value with In-situ Shearing Test and Notched Plate Tensile Test with Image Analysis [PDF]

open access: yesMATEC Web of Conferences
Critical damage values in Cockcroft and Latham's and Ayada's models are automatically identified using autonomous-driven finite element analysis (ADFEA). To validate fracture behavior, we perform in-situ shearing and tensile tests on notched steel plates,
