Automated Crack and Damage Identification in Premises using Aerial Images based on Machine Learning Techniques

2022 Sixth International Conference on I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC), 2022
The impartiality and reliability of evaluation, as well as the high time and expense demands, make it impossible to conduct a manual examination of infrastructure issues such as building fractures.

On finite damage: ductile fracture-damage evolution

Mechanics of Materials, 1985
Abstract The tensorial entities pertaining to the presence of a damage zone within a representative material sample are obtained from the micro-macro transition of kinematic quantities in finite deformation. It is shown that they reduce to a ‘small-damage’ tensor as the finite deformation measures reduce to their common infinitesimal counterpart ...

A cumulative damage model for bone fracture

Journal of Orthopaedic Research, 1985
AbstractA mathematical model is presented to describe the combined time‐dependent and cycle‐dependent fracture characteristics of devitalized cortical bone. Failure is interpreted based on a linear‐life fraction rule, which accounts for cumulative creep and fatigue damage under arbitrary loading histories.

A chain stretch-based gradient-enhanced model for damage and fracture in elastomers

Computer Methods in Applied Mechanics and Engineering
In this study, we introduce a novel stretch-based gradient-enhanced damage (GED) model that allows the fracture to localize and also captures the development of a physically diffuse damage zone.

A variationally consistent phase-field anisotropic damage model for fracture

, 2020
In the phase-field modeling of fracture in brittle and quasi-brittle solids, it is crucial to represent the asymmetric tensile/compressive material behavior. Existing phase-field models generally adopt either an intuitive split of the free energy density

Creep Damage and Fracture

1982
The creep data obtained during C0ST50, round II, have been reanalyzed according to the recovery creep model modified for precipitation strengthening mechanisms. A good description of creep data is obtained in this way for all cases studied. A dislocation climb bypassing mechanism is indicated as beeing the governing process in service applications of ...

Structural damage assessment of mountain tunnels in fault fracture zone subjected to multiple strike-slip fault movement

Tunnelling and Underground Space Technology, 2020
Fault fracture zones are adverse geological conditions often encountered in the constructions of mountain tunnels. Extensive structural damage to the mountain tunnels in adjacent to the fault fracture zones has been documented in the past earthquakes. In

Sacrum fractures and neurological damage

Journal of Neurosurgery, 1977
✓ Two cases are presented in which automobile collision caused transverse sacral fracture involving neurological elements. The patients were admitted within 2 weeks of each other to the Maryland Institute for Emergency Medicine. An attempt was made to assess the incidence of this condition and its relation to fractured pelvis.

Fracture and Damage

1985
After summarising the theory of damage of Rabotnov-Katchanov and its subsequent developments by Lemaitre and Chaboche, it is pointed out how this concept has been extended to ductile fracture in an overall manner, or by taking into account the physical mechanism of development of cavities. It is found that the rate of damage is proportional to the rate

Coupled thermo-damage and damage-fracture fields

1999
The creep process and the associated material deterioration are temperature sensitive phenomena. A classical approach consists in accounting for the effect of temperature on the material functions in the constitutive and the evolution equations of a damaged solid (cf. Ganczarski and Skrzypek, 1991), whereas the temperature field remains steady state.
