Base Acceleration in Harmonic Analysis – 3 Techniques and 1 ACT Extension
Harmonic analysis is a technique used to determine the steady-state response of linear structures to loads that vary sinusoidally (harmonically) with time. In harmonic analysis, the entire structure...

A response spectrum analysis is mainly used in place of a time-history analysis to determine the response of structures to random or time-dependent loading conditions such as earthquakes, wind loads,...

Piezoelectric actuators are widely used in a variety of industrial, automotive, medical, aviation, aerospace and consumer electronics applications. Your burger has been likely grilled on a gas BBQ...
View ArticlePiezoelectricity in ANSYS Mechanical, Say Goodbye to Command Snippets!
Piezoelectricity is the ability of certain crystalline materials to generate an electric charge proportional to a mechanical strain (direct piezoelectricity). Direct piezoelectricity was discovered by...
