Interface

class compas_assembly.datastructures.Interface

Bases: Data

A data structure for representing interfaces between blocks and managing their geometrical and structural properties.

Parameters:

size

points

frame

forces

mesh

Attributes:

pointslist[Point]

The corner points of the interface polygon.

sizefloat

The area of the interface polygon.

frameFrame

The local coordinate frame of the interface polygon.

polygonPolygon

The polygon defining the contact interface.

meshMesh

A mesh representation of the interface.

kernPolygon

The “kern” part of the interface polygon.

forceslist[dict]

A dictionary of force components per interface point. Each dictionary contains the following items: {"c_np": ..., "c_nn": ...,  "c_u": ..., "c_v": ...}.

normalforceslist[Line]

A list of lines representing the normal components of the contact forces at the corners of the interface. The length of each line is proportional to the magnitude of the corresponding force.

compressionforceslist[Line]

A list of lines representing the compression components of the normal contact forces at the corners of the interface. The length of each line is proportional to the magnitude of the corresponding force.

tensionforceslist[Line]

A list of lines representing the tension components of the normal contact forces at the corners of the interface. The length of each line is proportional to the magnitude of the corresponding force.

frictionforceslist[Line]

A list of lines representing the friction or tangential components of the contact forces at the corners of the interface. The length of each line is proportional to the magnitude of the corresponding force.

resultantforcelist[Line]

A list with a single line representing the resultant of all the contact forces at the corners of the interface. The length of the line is proportional to the magnitude of the resultant force.

resultantpointPoint

The point of application of the resultant force on the interface.
