Intersection of Convex Cones as Stress Range for Plane Normal Elastic Bodies
In this paper, the constitutive model of the normal elastic material has been generalized in order to describe stress states accounting for different strength characteristics in different directions. With this...

Article
Normal elastic and elastoplastic materials: from a comprehensive approach a mixed method for masonry
The article deals with materials with a constraint on the stress, which must belong to a closed and convex subset of the space of the second order tensors, called stress range. With particular reference to the...

Bounded shear stress in masonry-like bodies
In the paper, a hyperelastic material with limited tensile and compressive strength is considered. In addition, the maximum value of the tangential component of the stress that can be attained on each plane de...

A Direct Approach to Membrane Reinforced Bodies
The paper deals with membrane reinforced bodies with the membrane treated as a two dimensional surface with concentrated material properties. The membrane response is linearized so that it depends linearly on ...

A numerical method for solving BVP of masonry-like solids
In this chapter, we shall first explicitly determine the solution to the constitutive equation of isotropic masonry-like materials (i.e., find the stress tensor T and the fracture strain E ...

Equilibrium Problems and Limit Analysis of Masonry Beams
We consider planar straight and curved masonry beams with the constitutive equation from Orlandi (Ph.D. thesis, 1999) and Zani (Eur. J. Mech. A, Solids 23:467–484, 2004). After stating some results about the solu...

Stress State for Heavy Masonry Panels with Openings
In this paper we study the equilibrium problem of rectangular panels with openings made of a no-tension (masonry-like) material, undergoing, besides their own weight, a uniformly distributed load on their top....

Singular equilibrated stress fields for no-tension panels
In this work we study the equilibrium problem for rectangular panels made of a no-tension material, clamped at the bottom, subjected to distributed vertical loads on the top, and to different types of lateral ...

On the Collapse of Masonry Arches
In this paper a constitutive equation for masonry arches is defined and its main properties are proven; in this equation to each pair of generalized strains (ε, κ), with ε the extensional strain and κ the curv...

A numerical method for solving equilibrium problems of masonry-like solids
This paper proposes a numerical method for the solution of equilibrium problems of solids which do not support tension. Some boundary-value problems are solved numerically and the solution obtained is compared...

Computation of the Crack Extension Energy Rate in Elasto-plastic Fracture Mechanics and Applications in Engineering
A central cracked elasto-plastic plate undergoing three blocks of alternate loads is examined. Use is made of a numerical procedure for the computation of the crack extension energy rate, appropriately defined...

Explicit solutions for complex tension-torsion tests in plasticity
For an elastic-plastic material obeying the clasical kinematic hardening rule of Melan, a deformation process reproducing the combined tension-torsion test of a thin tube is considered and the accompanying str...
