Interference and Diffraction02:18

Interference and Diffraction

52.3K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Band Theory02:35

Band Theory

17.2K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Attribution Theory

13.8K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

    Area of Science:

    • * Physics
    • * Materials Science
    • * Mechanical Engineering

    Background:

    • * Elastodynamic geometrical theory of diffraction (GTD) is used in ultrasonic nondestructive testing (NDT).
    • * Standard GTD has limitations with complex scatterer contours, leading to spatially nonuniform fields, especially at singularities.
    • * Defects in NDT often have complex, finite-length contours that are not well-approximated by GTD's assumptions.

    Purpose of the Study:

    • * To overcome the limitations of standard GTD for analyzing complex defect shapes in ultrasonic NDT.
    • * To develop and validate elastodynamic incremental models for more accurate prediction of edge diffracted fields.
    • * To provide a more physically representative model for scattered fields from finite-length defects.

    Main Methods:

    • * Development of two elastodynamic incremental models: an extension of the incremental theory of diffraction (ITD) and a Huygens principle-based model.
    • * Numerical testing of the developed incremental models.
    • * Experimental validation of the models in a 3-D configuration.

    Main Results:

    • * The incremental models predict a spatially continuous scattered field, unlike standard GTD.
    • * The models provide a more physical representation of the edge diffracted field for complex contours.
    • * Numerical and experimental results demonstrate the efficacy of the proposed methods.

    Conclusions:

    • * Elastodynamic incremental models offer a significant improvement over standard GTD for ultrasonic NDT of complex defects.
    • * These models enhance the accuracy of scattered field prediction, crucial for defect characterization.
    • * The validated incremental models are promising for advanced NDT applications involving intricate geometries.
