Symposium Technical Description

The structural integrity is the ability of the structure to perform the designed task, for example, structural load carrying capacity, thermal barrier, and lift. Damage is defined as a process or an inclusion that compromises the structural integrity of the structure. The objective of this symposium is to bring together researchers from diverse backgrounds to investigate measurements of such damage and degradation in solid materials using various assessment methods. This symposium features new discoveries and advances in the fields of damage and degradation in solid materials, with an emphasis to bring together leading research scientists and engineers to present their work and foster new ideas about developing the state-of-the-art experimental tools and modeling approaches. This symposium welcomes contributions that report damage and degradation from both theoretical and experimental perspectives with emphasis on the following topics:

  • Health Monitoring of Structures and Materials (Diagnosis and Prognosis).
  • Nondestructive Damage Assessment Methods such as Infrared Thermography, Acoustic Emission, Ultrasonic, Digital Image Correlation, Fiber Optic, Vibration and etc.
  • Reliability Model Development (Accelerated Degradation Testing and Probabilistic Physics of Failure Model Development).
  • Elements of structural health monitoring: sensor selection, feature extraction and signal processing of damage related signals, statistical analysis of the damage features, probabilistic model development, and pattern recognition.
  • Modeling failure and damage in solids (Fracture Mechanics, Continuum Damage Mechanics, Thermodynamics, Statistical Mechanics and Information Theory based Models).
