Effective Element Thickness and Small Shear Area Calculation in SHAPE-THIN

SHAPE‑THIN calculates a very small shear area. What is the cause?

Answer:

The shear area is calculated as follows:

Ay = Iz2∫A*Szt*2dA*

Iz

Second moment of area in relation to the axis z or y

Sz

First moment of area in relation to the axis z

t*

Effective element thickness for the shear transfer

A*

Surface area based on the effective shear thickness t*
Shear Area Ay

Az = Iy2∫A*Syt*2dA*

Iy

Second moment of area in relation to the axis y

Sy

First moment of area related to the axis y

t*

Effective element thickness for the shear transfer

A*

Surface area based on the effective shear thickness t*
Shear Area Az

The effective element thickness for the shear transfer t* has a significant influence on the shear area. Therefore, the defined effective element thickness for the shear transfer t* (Image 01) of the elements should be checked.
