Identify the modes, MD, or submodes, SD, of corrosion

The matrix in Figure 4 shows possible modes and submodes at the heads of the columns or along the abscissa of the LAM. These are derived from the "Mode Definition" step of the CBDA as applied to specific subcomponents.

It is not necessary that each or all of these modes and submode apply to each LAi. Where these may not be applicable, this cell is left blank or crossed out. A mode that is relevant to one LAi may not be to another.

After the credible cells are identified and non-applicable modes are omitted, the LAM is ready to be evaluated.
