DAMAGE TYPES & PARAMETERS

Heart Damage/Rot

One input item is required to describe the degree of Heart Rot:

  • Shell Thickness: Minimum shell thickness (inches). D-Calc 5 assumes that the Heart Rot is concentric and, therefore, that this thickness applies to the entire circumference.

Shell Damage/Rot

One input item is required to describe the degree of Shell Rot:

  • Damage Depth: radial depth (inches) of the damage relative to the original surface of the undamaged pole


    image

Pocket Damage/Rot

Three input items are required to describe Pocket Rot:

  • Pocket Diameter: Diameter (inches) of the pocket
  • Shell Thickness: Minimum thickness (inches) of the wood at the point where the pocket comes closest to the pole’s surface
  • Angle to Min Shell: Angle (degrees) of the pocket relative to the line direction

Note: You can input the angle through the text box or by clicking on the Set button in the bottom-right, and then clicking on the pole graphic. Then click Done after setting the angle. This applies to Pocket Damage, Wedge, Section, Slice, Woodpecker Cavity, and Bolt Hole.

Misc. Damage - Wedge

To describe Wedge damage input:

  • Circumference Missing: circumferential extent (inches) of the damage

  • Depth Missing: radial depth (inches) of the damage

  • Angle to Damage: the angle (degrees) of the damage relative to the line direction

Misc. Damage - Section

Three input items are required to describe Section damage:

  • Depth Missing: radial depth (inches) of the damage

  • Circumference Missing: circumferential extent (inches) of the damage

  • Angle to Damage: the angle (degrees) of the damage relative to the line direction

    Note: The Misc. Damage – Section damage type can be used with a non-zero shell thickness, in other words, a wedge under the surface. This could be used to model the effects of a wedge-shaped interior rot, or something similar, where the Pocket Damage type does not sufficiently describe the shape. To do this, input a non-zero Shell Thickness, a Depth Missing greater than the Shell Thickness, and any Circumference.

Misc. Damage - Slice

Two input items are required to describe Slice damage:

  • Depth Missing: radial depth (inches) of the damage

OR

  • Width Missing

AND

  • Angle to Damage: the angle (degrees) of the damage relative to the line direction image

Woodpecker Cavity

Four input items are required to describe a Woodpecker Cavity:

  • Circumference Missing: circumferential extent (inches) of the damage
  • Shell Thickness At Opening
  • Nest Diameter: inner nest diameter (inches)
  • Angle to Opening: the angle (degrees) of the opening relative to the line direction

Bolt Hole

Two input items are required to describe a Bolt Hole:

  • Hole Diameter
  • Angle At Opening: the angle (degrees) of the hole relative to the line direction
