PARAM, NBZRCSR

Bulk Data Entry Identifies whether the Number of Peaks or Number of Zero Crossings are used for NARROW band model in Random Response Fatigue Analysis.

Parameter	Values	Description
`NBZRCSR`	<YES, NO>	YES (Default) Number of Zero Crossings is used. $n_{z c r o s s} = \sqrt{m_{2} / m_{0}}$ $n_{z c r o s s} = \sqrt{m_{2} / m_{0}}$ NO Number of Peaks is used. $n_{p e a k s} = \sqrt{m_{4} / m_{2}}$ $n_{p e a k s} = \sqrt{m_{4} / m_{2}}$ Where, $m_{i}$ $m_{i}$ is the moments of the output PSD from Random Response Analysis. Refer to Random Response Fatigue Analysis in the User Guide for more information.

<YES, NO>

YES (Default): Number of Zero Crossings is used.; $n_{z c r o s s} = \sqrt{m_{2} / m_{0}}$ $n_{z c r o s s} = \sqrt{m_{2} / m_{0}}$
NO: Number of Peaks is used.; $n_{p e a k s} = \sqrt{m_{4} / m_{2}}$ $n_{p e a k s} = \sqrt{m_{4} / m_{2}}$; Where, $m_{i}$ $m_{i}$ is the moments of the output PSD from Random Response Analysis.
