During operation of a shipping container handler, a twistlock pin supporting one side of two stacked shipping containers fractured, causing the shipping containers to fall. An investigation revealed that the alloy steel pin had a ferritic/bainitic mi

Grain size variations are common in thermomechanically processed alloys with non-uniform cold work. A method to produce samples with grain size gradients was developed using Incoloy 800H. Two tensile samples with non-uniform gages were designed with

Low-cycle fatigue (LCF) failures can be expected when rebars are subjected to a small number of cycles at large stress/strain amplitudes. Major seismic events are often preceded or followed by other events of smaller/larger magnitude. During each eve

As part of a steering linkage mechanism in a jet boat, two D-ring shackle pins were safety wired together in order to prevent either of the shackle pins from falling out. Relative movement of the D-ring shackles from maneuvering the boat caused fluct

The 2010 and 2011 Christchurch seismic events have highlighted the limitations of the current knowledge in assessing the residual capacity of earthquake-damaged reinforced concrete (RC) buildings. An important challenge during the assessment phase wa
