Example for the Calculation of the Compression-E-Modulus
Example for the Calculation of the Compression-E-Modulus
Given:
specimen (lxwxh)
40x40x160 mm
area under pressure (A)
1600 mm²
measuring length (L
0)
100 mm
Force min. (F
1
)
0,5 � 800 N
Force max. (F
2
) = 30%
25,5 � 40800 N
of the expected breaking
load
This results in:
∆ F � 40000 kN
Extension (L ) on F
0,002 mm
Extension (L ) on F
0,145 mm
This results in:
∆ L � 0,143 mm
This example results in the following E-modulus:
This example results in the following E-modulus:
ED =
∆
F x L
0
40000 N x 100 mm
∆
L x A
0,143 mm x 1600 mm²
or ED = 17482,5 MPa
0
= 17482,5 N/mm²
