Compressive strength - Wikipedia

In mechanics, compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size (as opposed to tensile strength which withstands loads tending to elongate). In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).

Mechanical Comprehension ASVAB Study Guide

Tension is a force that stretches or elongates something. When a cable or rope is used to pull an object, for example, it stretches internally as it accepts the weight that it's moving. Although tension is often treated as applying equally to all parts of a material, it's greater at …

Combined upper–lower bound analysis for shear strength of ...

The Modified Compression Field Theory (MCFT) has reasonably described the detrimental effects of axial tension. It is used to assess existing structures and to design new structures. Nevertheless, in the case of shear assessment under axial tension, the semi-empirical nature might elicit a discrepancy with several test results .
