Such brittle fractures
most commonly occur in dynamically loaded ferritic materials with body-centered- cubic, or bcc, crystal structure in which an imperfection serves as a stress concentrator.
Maximum circumferential stress criterion of brittle fracture
at the interface edge of bonded materials, Journal of Hefei University of Technology 30(2): 200-202.
of fibres in continuous fibre reinforced composites subjected to tensile loading in the direction parallel to the fibres has been predicted by means of the theory developed in .
As can be seen, we observed brittle fracture
for samples showing a low dissipalion of energy (Tilde10 kJ/[m.sup.2]).
Propagation in the brittle fracture
mode is related to crack speed and arrest occurs if speed falls below de-compression speed.
However, under certain conditions of stress-state strain rate and temperature, brittle fracture
can occur without a significant plastic flow prior to fracture.
The area under the curves after maximum force for 100/0, 90/10/0, 90/10/0, and 70/30/0 compositions much higher than that of prior to maximum force indicating that crack propagation is slow with higher energy absorption associated with toughness differ from 90/0/10, 70/0/30, and 70/15/15 compositions which exhibited brittle fracture
This investigation compares the indirect tensile high-strain rate brittle fracture
with quasi-static ductile response.
During long time service the embrittlement leads to the decrease of critical flaw size of brittle fracture
and to the reduction of the remaining life of a pressure vessel.
* higher corrosion and temperature resistance of Advantex over conventional E-glass, reducing brittle fracture
The relation [[rho].sup.*] = (1/2[pi])[([K.sub.Ic]/[[sigma].sub.Y]).sup.2] with yield limit [[sigma].sub.Y] (approximately equal to the ultimate strength in the case of brittle fracture
) given by Neuber [1-3] is conformed with the "critical distance approach."
The other is the brittle fracture
which occurs unstably with small displacement.
These include ductile overload, brittle fracture
, impact, fatigue, wear, and erosion.
They proposed that the variations in brittle Fracture
stress are related to the density of tie molecules: the higher this density, the higher the brittle fracture
