Fit Prony series, compare interlayers, mesh cross-sections, run a 4-point bend. Real data. Real solvers. Nothing to install.
Built for the everyday workflow of a structural glass engineer — from picking the right interlayer, to fitting a Prony series, to verifying a 4-point bending test in the lab.
Fit a Prony series to the relaxation function of a polymeric interlayer at any temperature. Output: ready-to-use coefficients for ANSYS or Abaqus, in seconds.
Same fit, for interlayers made of two or more bonded polymers — composite stacks, acoustic + structural pairs. One combined Prony series, ready for ANSYS or Abaqus.
Linearised thermal buckling of a PVB/PDLC/PVB sandwich plate. A 3D hexahedral FE model (H8RH + H8 full) gives the critical multiplier and the wrinkling mode shape — so you can size the laminate before the PDLC core starts to wrinkle in service.
Model temperature gradients through a laminated cross-section under real solar loads, seasonal swings, and shadow patterns. Predicts the thermal stress that builds when polymer interlayers and glass plies expand differently — the failure mode most facade designs miss until it's installed.
Run a four-point or three-point bending simulation on a laminated glass beam, with the real polymer relaxation at any temperature and any load history. Compare your lab measurements to a fractional-viscoelastic prediction — all in one five-phase wizard, validated against EN ISO 1288-3.
Verified against manufacturer datasheets. Validity envelopes from published 10–11 element Prony fits. Compliant with ISO 6721-10, EN 16613:2025, and EN 16612:2019 Annex D.

Two PhDs from Parma — one in structural mechanics, one in thermal analysis. Between us we've spent years inside Saint-Gobain, Kuraray, and the labs that publish the standards your facade has to meet.
