Which is more stronger in bending fracture
Compression or tension
On bone and why ???

Both cortical bone and trabecular bone are stronger in compression than tension, which reflects the fact that the inorganic phase is stronger in compression than tension. The organic phase contributes to the ductility and toughness of the tissues. ... The latter is often referred to as the fracture toughness.

Explanation:
