FEA: Time of Flight Diffraction (TOFD) of an Anisotropic Weld

Kevin Chan Blog 0 Comments

Summary of the PZFlex TOFD Simulation This example shows a typical Time of Flight Diffraction (TOFD) inspection of an anisotropic weld. TOFD is a flexible technique, which relies on a range of mode converted signals to be effective. PZFlex combines the capability of accurately simulating mode conversion in arbitrary geometries, with the speed to run large batches of TOFD models, …

PZFlex: Finite Element Analysis (FEA) Software that’s Fast and Efficient

Kevin Sandlin Blog 0 Comments

Today, we relaunch PZFlex as its own business. Previously, the FEA software maker was a division of Weidlinger Associates, Inc., and then Thornton Tomasetti after their merger. PZFlex has operations in Cupertino, CA, Glasgow, Scotland, and Atlanta, GA. We made the decision to launch PZFlex on its own for these reasons: Speed: PZFlex completes FEA in a tiny fraction of the time …
