T-Structures


The structure is obtained iteratively, by mixing laminates of two of the initial materials with the third one.

The field inside each material is constant, which makes this structure the simplest of the multi-material structures. The only two-materials structure with this property is laminate.

The variety of effective properties of a T-structure  is defined by the volume fractions of materials  m1, m2  (these materials are in the first-rank (inner) layers), and m3 - the  material in the second-rank (outer) layer, and by the angle  a of inclination of the second-rank layer.
 

Insert
m1 = (no default value)
m2 = (no default value)
m3 =    (m3 = 1 - m2 - m3)
  a =     default value  a = 0 : Orthogonal layers.

The structure is computed sequencially. First, laminates of materials 1 and 2  are computed; the volume fraction are m1/(m1+m2) and m2/(m1+m2) , respectively. Then, the obtained composite is laminated with material 3.
