Important contributions to research

  • Introduction of photoelasticity to the laboratory in 1928 and remarkable contributions to the development of the method manifested, e.g., by the monographs ´L. Föppl, H. Neuber:  Festigkeitslehre mittels Spannungsoptik  - strength of materials by photoelasticity´(1st ed. 1950)
  • Contributions to elasticity (exact analytical solutions of boundary value problems)
  • Introduction of electrical methods for the measurement of mechanical quantities at the laboratory
