mmmm, I have read that there are some materials with negative poissons ratios that are man made-some, weird types of foam for example...let me try and find the website that I saw it on. I realize that if poissons ratio=0.5 then K, the Bulk modulus will be infinite meaning the material is...

I'm doing A2 course work on properties of materials and have been looking at Youngs modulus, Bulk modulus, Poissons ratio and Shear stress strain etc.:rolleyes: Was wondering if any kind person would be able to explain why Poissons ratio has theoretical limits of -1 to 0.5? Have tried to search...
