• Calculation of Elastic Modulus
After the execution of the ramp which is determining the elastic modulus the value of the elastic modu-
lus is printed out by a connected printer
Example:
ELASTIC MODULUS 32250 N/mm
CUBE 150,0 mm
EXTENSION 1 0,001 mm
LOAD 1 0,5 N/mm
EXTENSION 2 0,101 mm
LOAD 2 22,0 N/mm
MEAS. LENGTH 150 mm
AGE 30 Tage
TESTER 5
ORDER 98123
IDENT 1
DATE 23:01:98
and, at the same time, is shown at the test screen:
Calculation Formula for the Elastic Modulus
∆F Lo
∗
∆D fp
∆F = force difference
∆D = deformation difference
Lo = measuring length
fp = specimen's area of cross section
