Composites analysis

Case Studies

LUSAS Composite is used by engineers in the automotive, aerospace, marine, defence, manufacturing and general mechanical industries for all types of composites engineering analysis from simple failure prediction using a number of failure criteria including Tsai-Hill, Hoffman and Tsai-Wu through to advanced delamination failure modelling. Most recent case studies are at the top.

Glass Reinforced Plastic (GRP) and Aluminium Bolted T-Joints

  • Parametric studies of bolted joints for yield and fatigue assessments.


"It was very useful to use LUSAS for this research work. I found it very intuitive."

Mike Gower, Research Scientist, National Physical Laboratory

Estimating impact damage in honeycomb sandwich panels

  • Development of a damage material model to simulate core failure in sandwich panels under a range of impact loading.


Carbon fibre mast, turret and boom components for a new yacht rig

Optimisation of rig design using linear buckling analysis, composite analysis and material testing.


"With the associative modelling capabilities of the LUSAS Composite modeller, design changes were easily incorporated into the finite element models. This resulted in rig components that were designed to the client's specification, had a high reliability, and were optimised for the imposed loadings".

Peter Schwarzel, Carbonworks

Composite landing gear struts

  • Development of composite landing gear components with the aim of reducing the cost and weight of future landing gear assemblies.


Composite wingsail design

  • Examination of stress distribution in the trailing section of a proposed new wingsail.


"By using LUSAS Composite for this analysis Walker Wingsail Systems were able to go into the prototype build stage with enhanced confidence in a very satisfactory lighter design."

Composite radomes

  • Evaluation of natural frequencies, and the effects of vertical and inclined plane shock loadings, and wind loading


Composite floor panels

  • Analysis of honeycomb sandwich floor panels designed to support Land Rover wheel loads in military aircraft.
