What strain results are shown in Sherlock's viewers?

Post by natalieh » 10 Apr 2019, 14:06

The 2D layer viewer displays PCB (board) strains -- these are equivalent surface strains.

In the 3D viewer, the average of the nodal strains in an element is displayed.

On a related note, in Sherlock's results tables, the table generally shows the maximum component or lead strains depending on the table selected (components or leads). Please note: the overall max component strain comes from the node on the PCB surface that is under the part.

When lead modeling is enabled for any FEA, the Lead results table is also produced:
• The Max Lead Strain column is the maximum strain seen for all nodes that make up the lead.
• The Max PCB Strain column is the maximum strain seen for the given lead at the PCB surface.
• The Max Part Strain column is the maximum strain seen for the given lead at the part surface.

In vibration results specifically, the table shows the maximum strain experienced by the component and lead, whichever is more. The vibration analysis is the only analysis where the lead strain can replace the component strain in the results table.
