Finite element consultancy

Zentech provides engineering consultancy services for the application of the finite element method to a range of industrial problems. These include the use of our own Zencrack software for applications that may involve cracks or crack growth prediction.

Our consultancy services on a range of commercially important applications include:

  • forensic analysis to examine the effect of roll and mis-alignment of the roller bearing on fatigue crack growth development
  • damage tolerance assessment in aircraft engine components
  • modelling defects starting from sub-surface inclusions in a spherical roller thrust bearing assembly
  • linear and non-linear analyses to determine allowable residual strength criteria for vehicles with in-service flaws
  • creep and fatigue crack growth modelling in high temperature nuclear power plant components
  • fatigue analysis of riser hang-off structure for an offshore field development
  • analysis of drop-load on a subsea structure
  • laying of pipelines and riser systems.
