Compressive

ASTM D695M

Test Specimens

< Compression Test Specimens for Materials Lees than 3mm Thick ,mm >

* Speed of Testing : The standard speed of testing shall be 1.3±0.3 mm(0.050±0.010in)/min. After the yield point has been reached, it may be desirable to increase the speed from 5 to 6 mm/min(0.20 to 0.35 in/min) and allow the machine to run at this speed until the specimen breaks. This may be done only with relatively ductile materials and on a machine with a weighing system with response rapid enough to produce accurate results

Calculation

* Compressive Strength [MPa]

* Modulus of Elasticity [GPa]
dividing the compressive represented by the point by corresponding strain,
= stress/stain
