1. Modeling of Scattering by Cracks in Anisotropic Solids - Application to Ultrasonic Detection
Sammanfattning : Elastodynamic wave scattering in anisotropic solids with application to ultrasonic nondestructive testing (NDT) is treated and mathematically modeled in this thesis. The scatterers are infinite strip-like cracks and the solids are homogeneous and linearly elastic with negligible damping. LÄS MER
2. Elastic Wave Propagation in Anisotropic Media. Application to Ultrasonic NDT
Sammanfattning : The subject of this thesis is elastic wave propagation in anisotropic materials with application to ultrasonic nondestructive testing (NDT). The first part of the thesis is concerned with modeling of ultrasonic transducers and wave propagation in anisotropic materials in general. First, a scalar 2-D case is considered. LÄS MER
3. 2D hybrid modeling of defects in an ultrasonic inspection situation
Sammanfattning : Advanced methods of nondestructive evaluations (NDE) are widely used for in-service inspection in many industrial applications, e.g. nuclear and aerospace industries. In these applications the components are exposed to different degradation mechanisms (e. LÄS MER
4. On minimally invasive treatment of Dupuytren's contracture
Sammanfattning : .... LÄS MER
5. Modelling of ultrasonic testing for cracks near a non-planar surface
Sammanfattning : Nondestructive testing using ultrasound has important applications in e.g. the nuclear power and aerospace industries, where it is used to inspect safety-critical parts for flaws. LÄS MER
