Damage Detection in Ceramic Materials Using Bicoherence Analysis

Application of All Ceramic Materials in Dentistry

The daily increase in Patientschr('39') demand for cosmetic treatments has led to dental restorations moving towards the use of all-ceramic materials. The development of all-ceramic restorations over the last decade has revolutionized aesthetic dentistry. Recent advances in ceramic manufacturing and processing methods have led to the evolutionary growth of all-ceramic materials with superior bi...

Damage Detection in Beam-like Structures using Finite Volume Method

In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...

Damage Detection in Post-tensioned Slab Using 2D Wavelet Transforms

Earthquake force, loading more than structural capacity, cracking, material fatigue and the other unpredicted events were undeniable in the structure life cycle in order that environmental conditions of the structure would be changed and treats health. Damage of structures such as crack, corrosion of the post tension cables from inappropriate grouting of the post tension structures and etc. can...

Defect detection in ceramic materials by quantitative infrared thermography

In this paper infrared (IR) measurements and dedicated signal processing algorithms were developed and applied for defect detection on green ceramic tiles. Tiles with defects having known dimension and position were realized and tested by acquiring either heating and cooling transients of the tile subjected to thermal pulse excitation. As rarely defects appear directly in the thermal map, post-...
