   The Analysis Explorer dialog opens.

   Tip: Use the chevron next to each option to view all options for runs, operations, and result types.
2. Select a run to analyze.
3. Select an operation.
4. Select a result type:

   Result Type	Description
   Thinning	Thinning is the ratio of the change in thickness to the original thickness expressed as a percentage. A positive thinning percentage indicates a reduction in thickness, which could be of concern for the performance of the part under fatigue loading since thinner regions in the part will undergo higher stresses compared to the rest of the part. A negative thinning percentage indicates thickening of the part in regions of compression. Excessive compression may lead to wrinkles on the sheet metal, resulting in poor surface quality.
   Thinning Delta	Thinning due to deformation in the current operation only, ignoring history.
   Major Strain	Major strain is the principal strain on the surface of the sheet metal due to the deformation of the initial blank shape to the finished product. The red areas indicate greater stretching relative to the blue areas. When you choose this option, a field appears for you to view results based on a particular material surface. Under Result Types, from the Major Strain dropdown, select a surface: Lower, Upper, or Membrane (middle). By default, tensor directional arrows are displayed. Toggle on and off in Show> Options.
   Minor Strain	Minor strain is the principal strain on the surface of the sheet metal due to the deformation of the initial blank shape to the finished product. The red areas indicate less compression relative to the blue areas. When you choose this option, a field appears for you to view results based on a particular material surface. Under Result Types, from the Minor Strain dropdown, select a surface: Lower, Upper, or Membrane (middle). By default, tensor directional arrows are displayed. Toggle on and off in Show> Options.
   Edge Strain	Edge strain is the strain along the local edge tangent direction.
   Strain Tensor	View both major and minor strain tensors plotted together. By default, tensor directional arrows are displayed. Toggle on and off in Show> Options.
   Curvature	Element curvature due to bending during forming. Includes principal and local values.
   Dominant Deformation	Indicates dominant deformation mode during forming. Ranges from 0 to 1, with 0 indicating stretching, and 1 indicating bending.
   Equivalent Stress	Equivalent plastic stress is the stress on the surface of the sheet due to the deformation of the initial blank shape to the finished product. The red areas indicate more deformation relative to the blue areas.
   Formability	The principal strains on the surface of the sheet metal, also known as Major and Minor strains, are plotted against a Forming Limit Curve to identify different deformation zones that occur during the stamping process. Each color indicates a unique deformation zone during stamping. Red: High potential for failure from splitting due to excessive deformation. Yellow: Marginal potential for failure. View the percentage for Absolute and Relative. Green: Safe with no potential for failure. Blue: Material is compressed. Violet: Wrinkling zone with potential for failure. Cyan: Loose metal zone indicates that material is not sufficiently deformed. View the percentage of loose metal next to the color. When you choose this option, a field appears for you to view results based on a particular material surface. Under Result Types, from the Formability dropdown, select a surface: Lower, Upper, or Membrane (middle).
   Failure	Failure is estimated from the Forming Limit Diagram. The failure is the relative distance of the major and minor strain at a point on the Forming Limit Curve as shown in the example. A value less than one indicates no failure and above one indicates failure. When you choose this option, a field appears for you to view results based on a particular material surface. Under Result Types, from the Failure dropdown, select a surface: Lower, Upper, or Membrane (middle).
   Plastic Strain	The plastic strain of the sheet is the measurement of the deformation from the initial blank shape to the finished product. The red areas indicate there is more deformation relative to the blue areas. When you choose this option, a field appears for you to view results based on a particular material surface. Under Result Types, from the Plastic Strain dropdown, select a surface: Lower, Upper, or Membrane (middle).
   Plastic Strain Delta	Thinning due to deformation in the current operation only, ignoring history.
   Thickness	Thickness is the actual material thickness distribution in the part. The thinning percentage is directly derived from the thickness distribution.
   Displacement	For a draw or crash form operation, displacement is the distance that the flat blank moves from its initial shape to its final shape. For a springback operation, displacement is the distance that the final blank shape moves back toward its intial shape. Choose the Magnitude, Global X,Y, Z, or +/- Magnitude. +/- Magnitude is available for the springback operation only. Positive magnitude indicates displacement along the normal direction; negative magnitude indicates displacement in the opposite direction of the part normal.
   Skid Marks	Skid Marks indicates the likelihood of tool marks or skid lines. The results range from zero, no chance, to one, very likely. When you choose this option, a field appears for you to view results based on the impact of each tool. Under Result Types, from the Skid Marks dropdown, select a tool: Top Die, Bottom Die, or Binder.
