HBL Ltd : Impact Analysis of a Golf Ball
HBL Ltd was a small self-funded company set up by Iain McCreary and Rani Osnat, with intellectual property contributions from Qinetiq, and engineering support from Plextek Ltd. HBL's intent was to provide real time, three dimensional tracking of golf balls in flight, giving accurate feedback on speed, spin, shot shape and curvature, in-air and on-ground distance.
HBL requested that IDAC predict the impacted behaviour of a golf ball containing a wide-band microwave transmitter unit. The impact analysis would be used to answer four sets of questions: 1.) How do golf balls behave under impact? ... (More)

National Physical Laboratory : Parametric Calibration Analysis of an Atomic Force Microscope
The Atomic force microscope (AFM) is a very high resolution-scanning microscope and is used at NPL laboratories for imaging the surface of materials in the micrometer to nanometer length scales.
IDAC created a parametric model using ANSYS where the AFM probe was modelled by means of 8- noded 3D elements with large strain large deflection capability. The top surface of the cantilever was then coated with 4 noded shell elements to simulate the 30-50 nm thick layer which coats the device. The effect of the..... (more...)

Technip & CRP : Bend Stiffener Analysis for the BP Schiehallion Project
With a workforce of 22,000 people worldwide, TECHNIP ranks among the 5 major players in full-service engineering and construction services in the field of hydrocarbons and petrochemicals.
IDAC was approached to carry out an analysis to evaluate the behaviour of the risers under different degree slippages of the stiffeners and to assess what, if any, damage would occur to the riser. The analysis was carried out with a view to sending divers down to carry out remedial work.
In the end of the analysis IDAC redesigned the companies IDS and no divers were required in the replacement operation.
