2.2 Element Load Specification
1) Joint loads at element nodes in global directions.
2) Concentrated loads at any user specified point within the
3) Uniform pressure on element surface in global or local
4) Partial uniform pressure on user specified portion of element
5) Linearly varying pressure on element surface in local
2.3 Theoretical Basis
1) Displacement compatibility between the plane stress component of
2) The out of plane rotational stiffness from the plane stress
3) Despite the incorporation of the rotational stiffness mentioned
4) These elements are available as triangles and quadrilaterals,
5) These elements are the simplest forms of flat shell/plate
6) These elements may be connected to plane/space frame
7) Out of plane shear strain energy is incorporated in the
8) The plate bending portion can handle thick and thin plates, thus
9) The plane stress triangle behaves almost on par with the well
10) Stress retrieval at nodes and at any point within the element.
2.4 Element Local Coordinate System
1) The vector pointing from I to J is defined to be parallel to the
2) The cross-product of vectors IJ and IK defines a vector parallel
3) The cross-product of vectors z and x defines a vector parallel to
4) The origin of the axes is at the center (average) of the 4 joint
2.5 Output of Element Forces
1. All element stress output is in the local coordinate system.
2. To obtain element stresses at a specified point within the
