Aluminium Honeycomb Composite Structure

Aluminium Honeycomb Composite Structure

Kevin Chan Blog 0 Comments

Summary of the Aluminium Honeycomb Simulation The video shows a pressure load applied to the top Carbon Fibre Reinforced Polymer (CFRP) skin layer on a curved aluminium honeycomb structure. The plot of velocity magnitude (z-component) allows us to visualize the propagation of the wave through a non-defective component. The microstructure of composite structures significantly increases the complexity of simulating wave …

High Intensity Focused Ultrasound (HIFU) Tissue Maps Simulation

Andy Tweedie Blog 0 Comments

Summary of the PZFlex HIFU Simulation The video demonstrates the acoustic solve for a High Intensity Focussed Ultrasound (HIFU) simulation. We generate the model from an imported tissue map of a human abdomen from the Visible Human Project. Calculating the thermal dose delivered by therapeutic treatments is dependent on many factors, and can be a complex process. PZFlex combines piezoelectric, acoustic, …

Flextensional Transducer

FEA of the design of a Class IV Flextensional Transducer

Andy Tweedie Blog 0 Comments

Summary of the PZFlex Flextensional Transmitter Simulation The simulation analyzes the design of a Class IV Flextensional transmitter using titanium caps to maximize surface displacement. The most popular deployments of flextensional transducers include low ultrasonic frequencies applications from sonar to surgical actuation. Flextensional devices are compact and achieve high vibration amplitudes for a relatively low piezoceramic volume making them ideal …

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 …
