Assessing the use of Circumferentially Notched Tension specimen for fracture toughness determination of ductile offshore steels

The Circumferentially Notched Tension (CNT) specimen is a potential candidate for determining the fracture toughness of highly constrained cracks, theoretically approaching plane strain conditions, even for small test specimen dimensions. This research aims to experimentally evaluate the use of the CNT test specimen geometry to fracture...

Mechanical Aspects of Wafer-Based Crystalline Silicon Solar Cells

The mechanical aspects of wafer-based crystalline silicon solar cells were investigated for cell bowing and mechanical strength. The cell bowing was investigated as a result of a silver or aluminium metallization layer applied for different production parameters. The residual stresses were calculated using a finite element (FE) model validated...
