The value of compressive stress
of the stone wool test specimens measured by different methods was similar, although the compress speed was doubly different.
The depth of the compressive stress
is a function of the kinetic energy imparted to the peened surface which, in turn, is a function of the mass times the velocity of the shot.
It was found that M/6/940 foam has a compressive stress
at 25% strain of approximately 2.
The maximum compressive stress
is located in the first interface, the heating to insulation interface, because of the very stiff oxide insulation and high temperature at this location.
It may just be mentioned, with no figure shown, that the magnitude of compressive stress
near the surface gets higher slightly as the mold closing velocity increases, which could be explained in the same way as in interpreting the results of Fig.
Initial evaluation was performed by monitoring long-term compressive stress
relaxation (CSR) at 150 [degrees] C (302 [degrees] F).
Figure 21 presents contours of the compressive stress
on the section of seal at 3.
Residual stresses were measured in free quenched polymethyl methacrylate (PMMA) and polycarbonate (PC) by applying the layer removal method, and, in all cases, a maximum compressive stress
and a maximum tensile stress were observed on the surface and in the core of the specimen, respectively (9).
The second edition is an overview of compressive stress
relaxation (CSR) tests developed in the rubber industry.
Two different shear creep tests were conducted (Series I, see Table 1): one with a superimposed constant axial tensile stress (Case 1) and another with a superimposed constant axial compressive stress
A polymer-polymer joint obtained by mechanical fastening at a compressive stress
of 5% (or less) of the 1% offset yield strength of the polymer (nylon-6) was found to exhibit irreversible decrease in the contact electrical resistance upon repeated fastening (loading) and unfastening [unloading].
This figure shows that compressive stress
at a given deflection is greatest for the adhered specimen (A); the response with sandpaper (S) is not too different.
In the context of craze damage, differences in [alpha] between materials may be taken to indicate that the compressive stress
causes more severe fibril damage in some materials than others.
In a conventional flexometer, the sample is subjected to a cyclic compressive stress
under constant static load and constant dynamic strain using a motor driven eccentric wheel.
In part I of this publication, the compression was imposed externally, which permitted direct investigation of the effects of the compressive stress
in different grades.
