Overall, grafted poly(IPA) in the IPA series clearly demonstrates enhancements in breaking tensile stress
, shape recovery, water compatibility, and temperature-sensitive control of water swelling and WVP.
Average tangential tensile stress
in the edge of the circular saw blade is also shown in Table 4.
Meanwhile, the dynamic tensile stress
away from the weld also rises slightly.
At the same time, due to moment equilibration, the internal moment caused by inner compressive stress area and the internal moment caused by outer tensile stress
area still remain equal as shown in Figure 2.
In these models, the maximum principal stress (FRD: 1.749 MPa, screwed-FRD: 1.370 MPa, TFBC: 0.686 MPa, and screwed-TFBC: 0.481 MPa) in the palatinal neck of the first upper molar is more active and hence the tensile stress
is observed in the palatinals of the first upper molar teeth.
In the elastic stage, a rising trend of the amplitude variation with the increase in the applied tensile stress
can be observed in the inductive state of the ECS, whereas a declining trend is observed in the capacitive state (Figure 4(a)).
By changing the tensile strength and shear strength between different particles layers (i.e., adding weak bedding planes to the model), 5 different models with different angles between the tensile stress
and bedding planes, namely, 0[degrees], 30[degrees], 45[degrees], 60[degrees], and 90[degrees], are established to simulate the different brittle characteristics of shale with different bedding plane angles (Figure 12).
Replacement with expansive admixture induces the reduction of shrinkage cracking and redistributes the tensile stress
in the specimen, which serves to improve the compressive strength as well as the bond performance in the splice zone.
(3) The inner surface of the arch rib web is pulled, and the maximum tensile stress
reaches 1.851 MPa at the age of 30 days, 2.964 MPa after 180 days, and then 3.363 MPa after 3600 days.
It reveals that at minimum value of welding current involves achieving maximum of tensile strength, maximum tensile stress
achieved with maximum value of welding current and welding speed.
The reason may be that the tensile stress
manifested on the inner wall and initially acted on the inner part [18-21].
The maximum tensile stress
that a material can withstand before failure is known as the tensile strength [[sigma].sub.c].
