With thermoplastics, the property of compressive strength at break is not always the relevant measurement, because for many ductile materials the specimen deforms without clear breakage. Excessive deformation under load would thus not be a good indication for success in any real industrial application. For these reasons, the compressive load is ...

Compressive Strength vs Tensile Strength . Often, people debate over the use of box compression tester with tensile strength tester. Well, there is no way with which you can estimate compressive strength if tensile strength is known or vice-a-versa. The two different instruments with two different principles are used to measure these parameters ...

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

compressive strengths. Material specifications for Polyiso Insulations (ASTM C 1289 in United States and CAN/ULC-S704 in Canada), indicate that all polyiso products should have a minimum stated compressive strength of 16 psi (110 kPa). Actual compressive strength may vary above the minimum depending on the manufacturer.

M.R. WISNOM, in Comprehensive Composite Materials, 2000. 5.03.4.1.1 Compressive tests. Compressive testing of composites is notoriously difficult, and despite the huge amount of research that has been undertaken, there are still many problems obtaining reliable and repeatable data for compressive strength. These issues are discussed by Adams in Chapter 5.06 this volume.

In toughened glass, compressive stresses are induced on the surface of the glass, balanced by tensile stresses in the body of the glass. Due to the residual compressive stress on the surface, toughened glass is more resistant to cracks, but shatter into small shards when the outer surface is broken.
