If the Poisson's ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

This is shown in the stress animation below. In this animation, the red vertical slider on the left indicates the amount of temperature increase. The blue shading on the rod indicates the level of ...

Research highlights the use of machine learning to assess compressive strength in concrete reinforced with steel fibers, enhancing sustainable construction.
