For larger engineering-size specimens that include millimetre-size pores, the strength of the material averages about 20 MPa (an elastic modulus of about 11 GPa).
Low cycle fatigue (LCF) properties of JLF-1 steel were studied from room temperature (RT) to 873 K in a vacuum condition using engineering size cylinder specimens with 8 mm in diameter.
The effects of clamping prestrain (0.15 and 0.3 engineering strain) and specimen geometry (5×5, 5×3.75, and 5×2.5 cm) were investigated.
Since schistose plane orientation is one of the key factors to control the formation of macro-cracks and hence failures of unloading test specimens, these engineering geological characters should be taken into consideration in engineering design.
To this end, various laboratory tests, including Hamburg wheel tracking test, Overlay test, indirect tensile strength test, resilient modulus test, and dynamic modulus test were performed to compare the engineering properties of PMLC specimens to those of plant-mixed and field compacted (PMFC) field core specimens at different aging stages.
In this paper, the tensile and fatigue properties of JLF-1 steel were studied from room temperature to 873 K in vacuum with engineering size round bar specimens.
In view of the effect of fissure water in fractured rock mass on the strength of rock mass in engineering projects, we prepared specimens of cement mortar to simulate saturated rock mass with continuous fractures of different slope angles.
In this paper, the low cycle fatigue properties of JLF-1 steel were studied from room temperature (RT) to 873 K in a vacuum condition using engineering size round bar specimens.
Therefore, this phenomenon is either totally neglected in extending laboratory test results on a small specimens to engineering design and analysis, or laboratory test results are simply distrusted and the design or analysis is based on empirical interpretations of in-situ field tests (e.g., SPT or CPT) which could also involve a wide range of uncertainties.
A simple method was proposed for evaluating the influence of mean stress on the fatigue limit of a cracked specimen using engineering approximations.
Stress-corrosion cracking is a delayed failure process wherein a crack initiates and propagates slowly until the stress in the remaining section of the test specimen or engineering component exceeds fracture strength.
