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

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

Cracks are created by massive breakage of molecular or atomic bonds. The latter, in its turn, leads to the highly localized loss of material, which is the reason why even closed cracks are visible by a naked eye.

Energy Evolution and Damage Mechanism of Fractured Sandstone with Different Angles
To explore the influence of crack angle on the mechanical properties, energy evolution, and damage evolution of sandstone, uniaxial loading tests were conducted on sandstones with different crack angles.
