How much force does it require to tear apart steel, iron

In the link we can see that iron has a tensile strength of 350 MPa, which means that it takes a force of 350 million Newton to pull apart a one square meter thick column of iron. Concrete is listed at 2-5 MPa and steel between 400 and 2700 MPa. It should be noted that while concrete doesn't resist tension well, it does resist compression well.

Fracture probability modelling of impact-loaded iron ore

Apr 01, 2017 The iron ore pellets are not perfectly spherical nor do all iron ore pellets have the same size, as shown in Table 1. To compensate for the size variations, the load F is divided by D 2 resulting in a stress-like measure and the deformation is divided by D,resulting in a strain measure for the experimental results.
