Experience Summary:

Considerable Stress Analysis experience using both Classical Methods

(e.g. hand calculations) and Finite Element Methods (e.g. NASTRAN, PATRAN,

ABAQUS, MARC, ANSYS, SC03) in linear, nonlinear, static, dynamic, aeroelastic

and thermo-mechanical stress analyses.

Experience in stressing both metallic and non-metallic (e.g. composite) materials.

Experience in creep life estimation and in fatigue life estimation using both, the S-N

curves 'safe-life' approach and the fracture mechanics 'damage-tolerance' approach.

Experience in operating systems such as UNIX, Linux, Windows and in programming

(e.g. Fortran). Currently developing own Finite Element package.
