For masonry, a No Tension Material NTM model can be adopted to compare with classic Heyman's results, but also a limited compressive and tensile strength with a cohesive frictional behavior in shear may be accounted for in a relatively simple fashion, i.e. in principle with the possibility to model shear sliding and compression crushing.

But a design flaw makes it uncomfortable (one end sags) as a piece of "tensioning" material anchored into the base keeps coming out.
The masonry is modeled as a no-tension material with infinite compression strength and sufficient friction to prevent the sliding, as introduced by Heyman (1966 , 1995.
The nonlinearity of the problem (no-tension material, frictional sliding and crushing) is concentrated in the interface between two adjacent blocks.
The arch is made of quadrangular blocks and the nonlinearity of the problem (no-tension material, frictional sliding and crushing) is concentrated at the interface between the blocks.
By employing a no-tension material model with linear behaviour in compression, new analytical, closed-form expressions for deformed shape of the structure, location of the neutral axis in a generic cross section and axial displacement are provided.
The analysis is based on the assumption that the material is unilateral, namely a No-Tension material in the sense of Heyman; in particular the safe theorem of Limit Analysis is employed.
One is based on a semi-analytical formulation of the relevant boundary-value problem for a no-tension material response; the other employs a plastic-damage-contact constitutive model, the CraftS model, to capture the complex microstructural behaviour of the material.
The damage evolution predicted by the models is also investigated for selected cases, showing that the formulation based on the no-tension material is able to capture with good agreement the damaged zone of the column for loads with low eccentricities.
Yokel (1971) has developed a solution for the deflection and stability of compressed members made with no-tension materials and elastic behavior in compression.
The following issues have to be considered during the selection of skirt materials: tension strength of material; tearing strength of material; anti-delamination capability of coating fabric; flexibility and anti-ageing capability of skirt cloths (nylon fabric coating); and the low temperature characteristic of skirt materials for situations where the crafts are operating on ice.
