The aim of this study is to investigate the low-cycle fatigue (LCF) properties of an AISI 304L welded joint based on experimental data. The influential parameters on the LCF such as the specimen thickness, strain ratio and cryogenic temperature were considered in this experimental study. In order to investigate the thickness effect on the LCF behavior, two types of specimens with thicknesses of 5 mm and 10 mm were used in an LCF test. In addition, the fatigue tests were conducted under strain control with three different strain ratios of R = −1, 0, and 0.5 at room and cryogenic temperatures. Based on the results obtained by this experimental study, no significant effect involved with the thickness and the strain ratio were observed. However, it was clearly observed that LCF performance at room temperature is lower than that at cryogenic temperature. Finally, an LCF design curve that can be used in design of the liquefied natural gas (LNG) applications is suggested.

Based on the self-made triaxial servo-controlled seepage equipment for thermo-hydro-mechanical coupling of coal containing gas, the experimental study on the thickness effect of composite coal and rock containing gas was carried out with the length of composite coal and rocks, confining pressure and gas pressure fixed, meanwhile change the thickness of sandstones and coal. The results show that the strain-stress curve of composite coal and rock containing gas has great identity with the typical strain-stress curve of coal or rock. The thickness effect does exist in the composite coal and rock, different thickness ratios between sandstone on top and coal have different effect on the peak strength of composite coal and rocks. When the ratio of sandstone on top to coal is close to 1.1, the extremum of the peak strength will appear more easily in the condition of the same coal thickness. The strength of composite coal and rocks will fall if the ratio is higher or lower than the ratio of thickness correspondence of the extremum, moreover, the speed of decrease is higher when the sandstone is thinner than the coal. The peak strength of composite coal and rocks varies between the strength of coal and the sandstone. The elasticity modulus of the rock-coal-rock body varies between the coal and sandstone, moreover, an extremum appears more easily when the ratio of sandstone on top to coal is close to 1.1. The poisson's ratios of composite coal and rocks are lower than sandstone, higher than coals. The results have a reference value in the support of half coal crag tunnel and the mechanical features of the composite coal and rocks containing gas.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
