Psylotech's post processor converts experimental data into Prony series form for numerical simulations. The experimental results thereby lay the foundation for deeper understanding of polymer mechanical behavior and can shorten product development time on everything from aerospace structures to downhole oil seals. Linear viscoelastic time and temperature dependence lay the groundwork for large deformation, non-linear viscoelastic theory development through finite element analysis.

Specifically, the software converts isothermal frequency sweeps into a material's viscoelastic, full 3D mechanical property matrix. Results can be output in:

• the frequency domain as dynamic moduli and dynamic Poisson's Ratio
• the time domain as modulus, compliance, or Poisson's ratio as a function of time
• temperature ramp format, where storage and loss moduli are plotted against temperature

Psylotech prefers isothermal frequency sweeps over creep, stress relaxation or temperature ramp testing, because frequency domain testing rejects noise and drift. Also, because isothermal testing ensures constant temperature through the specimen thickness. Moreover, conversion between properties is mathematically far easier. Anisotropic materials are accommodated through additional tests along orthogonal axes.
