Merged Web Properties

Record of web parameters

 Description The Merged Web Properties record specifies the parameters that define the mechanics of the web and its visualization.
 Usage A Merged Web Properties record defines the properties of the merged web based on law of mixtures. The Merged Web Properties record uses information from other Web Properties records. Example: A Merged Web Properties record is used the same way as a Web Properties record. Example:
 Equations The merged web properties are calculated according to the following equations: Thickness: ${\mathrm{th}}_{{}_{\mathrm{out}}}={c}_{r}\sum _{i=1}^{n}{\mathrm{th}}_{i}$ where subscript $\mathrm{out}$ is for the merged web, index $i$ is for the i-th incoming web, ${c}_{r}$  is the compression ratio, and $2\le n\le 10$ is the number of merging webs. Density: ${\mathrm{\rho }}_{{}_{\mathrm{out}}}=\frac{\sum _{i=1}^{n}{\mathrm{th}}_{i}{\mathrm{\rho }}_{i}}{{c}_{r}\sum _{i=1}^{n}{\mathrm{th}}_{i}}$ Modulus of Elasticity (assuming all webs have the same width): ${E}_{\mathrm{out}}=\frac{\sum _{i=1}^{n}{\mathrm{th}}_{i}{E}_{i}}{\sum _{i=1}^{n}{\mathrm{th}}_{i}}$ Poisson's ratio (assuming all webs have the same width): ${\mathrm{\nu }}_{\mathrm{out}}=\frac{\sum _{i=1}^{n}{\mathrm{th}}_{i}{\mathrm{\nu }}_{i}}{\sum _{i=1}^{n}{\mathrm{th}}_{i}}$ Damping ratio: ${d}_{{r}_{\mathrm{out}}}=\frac{1}{n}\sum _{i=1}^{n}{d}_{{r}_{i}}$
