Research on durability of underground lining structures using damage theory [PDF]

open access: yesScientific Reports
Damage and fracture theories have been widely applied to reinforced concrete structures. However, their application to the investigation of the durability of underground structures is still very limited.

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 ...

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,

On the lumped damage modelling of reinforced concrete beams and arches

open access: yesFracture and Structural Integrity, 2020
The analysis of reinforced concrete structures can be performed by means of experiments or numerical studies. The first way is usually quite expensive, so the second one sometimes is a good option to understand the physical behaviour of actual structures.
