The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test there is a linear region where the material follows Hooke's law.Hence for this region = where this time E refers to the Young's Modulus for compression.In this region the material deforms elastically and returns to its original length when the stress is removed.
Get Pricematerial is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material.
