Temporal Moments

Temporal moments are sometimes used for shock analysis.

Here is a Matlab script: temporal_moments.m

Here is a paper: From SRS to Temporal Moments

fixed_fixed_fixed_fixed_plate

The plate is aluminum, 0.063 inch thick.  The fixed edge lengths are 6 and 4 inches.

The vibration mode was calculated via the Rayleigh method using an assumed displacement function, as carried out via Matlab script:  fixed_fixed_fixed_fixed_plate.zip

The method is given in:  fixed_fixed_fixed_fixed_plate.pdf

NASGRO Coefficients

The following scripts calculate the A, B, C, P coefficients to model a set of SN curves with varying R values: sin_curve_fit_R.zip

sin_curve_fit_R.m is the main script.

The remaining scripts are supporting functions.

The equations are given in: sn_curvefit_equation.pdf
