Crystall Structure for Why Materials Tend to Fail in Tension

[rmrramani]

why lot of materials tend to fail in tension rather then compression?
please explain using crystall structure of material , suggest some pdf regarding to this topic

No material can fail in full compression. That is compression on all three axes at once.

Compression failures are actually because the compressive force is only applied on one or two axes and the failure is a response by shear failure in the non confined axes.

There are two types of tensile failure brittle failure which is an actual tensile failure and ductile failure which is again a shear failure.
