Structural design of plastic construction elements

Plastics (thermoplastics and duroplastics) are viscoelastic materials. The material properties are time, temperature and medium dependent. Additionally imperfections must be considered for duroplastics (GRP). Long term (extrapolated up to 50 years) and short term material properties must be taken in consideration for the structural design.


  • Consulting in plastic material aspects
  • Attendance of experiments
  • Structural integrity of plastic construction elements (pipes, manholes, tanks and special parts) using the analytic method
  • FEM calculations for special plastic construction elements with demanding geometry, e.g. molded parts and special components
  • Damage expertise and rehabilitation suggestions
  • Verification of structural calculations
  • Performing IHK (Chamber of Industry and Commerce) and EBA (Federal Railway Authority) expertise and damage expertise
