Course paper / final thesis

Optimization of Hybrid Plates

Starting date


Duration of contract

6 months

Your mission:

Hybrid metal-FRP-design attempts to combine advantages of both materials. Metal design in general leads to high surface quality, improved load introduction capability and low material cost. FRP offers high specific strength and stiffness and better fatigue behavior.

In the current study the weight saving potential of hybrid design shall be evaluated on a generic level. 

Therefore structural configurations, which can be found as sub-parts of thin-walled structures, are to be examined. One of those configurations is a hybrid plate loaded in axial compression with both transversal edges simply supported, one free longitudinal edge and the other elastically restrained (see Fig.). This could for example represent a flange of a stringer or beam.

Your tasks include:

  • implementation of analytical algorithms for stress and stability analysis of laminated plates
  • construction of parametric finite element models
  • optimization for minimum weight under stability and strength constraints
  • documentation and discussion of results

Your qualifications:

  • knowledge of analytical and numerical analysis of plates
  • basic programming skills
  • good knowledge of English (written and oral)

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Reconciling family and working life as well as equal opportunities for women and men are an integral part of our HR policy. We therefore strongly encourage applications from women. Disabled applicants with equivalent qualifications will be given preferential treatment.
