MSC Nastran SOL 146 ABAR Calculation

Formula

The formula to calculate ABAR is:

\[ \text{ABAR} = \frac{F}{A} \]

Where:

\( F \) is the force in Newtons (N).
\( A \) is the area in square meters (m²).

Example

Let's say the force (\( F \)) is 1000 N and the area (\( A \)) is 2 m². Using the formula:

\[ \text{ABAR} = \frac{1000}{2} = 500 \text{ N/m}^2 \]

So, the ABAR is 500 N/m².

What is ABAR?

ABAR (Axial Bar) is a measure used in structural analysis to determine the stress distribution in a bar element subjected to axial forces. It is calculated by dividing the applied force by the cross-sectional area of the bar.
