Why fracture toughness is a material property? Can I say that Fracture toughness is a material property only for plane strain case because it is independent of plate thickness?
Hi Kashif, fracture toughness is not a material property since it changes with changing material width. However, but as the material thickens and reaches to a critical thickness value, the plane stress conditions turn into plane strain conditions. As the thickness hits that value the fracture toughness of the material converges to a value which is named plane strain fracture toughness of the material. Any increase in the material thickness beyond that critical value will not lead to a major deviation from the plane strain fracture toughness value of that specific material. In other words, beyond that critical thickness value fracture toughness becomes independent of the materials thickness.
Hi Furkan, thanks for your kind words. We are planning to make videos specific to some materials and material groups, including composite materials, but in the upcoming weeks we will be releasing more videos on mechanical properties of materials.

Excellent work, thank you. I specifically liked the parts (DBTT and K_{IC}). Very well explained. 👍
Thanks for the video!
Informative 👍🏻
We are glad to hear that! Thanks!!

Hello sir, could you make some videos related to composite materials? Might be about microstructure or some properties.
Thanks for useful videos. 🙂
