An Experimental Investigation of Shale Mechanical

Mar 12, 2013 · Shale mechanical properties are evaluated from laboratory tests after a complex workflow that covers tasks from sampling to testing. Due to the heterogeneous nature of shale, it is common to obtain inconsistent test results when evaluating the mechanical properties. In practice, this variation creates errors in numerical modeling when test results differ significantly, even when

Effect of Deformation Temperature on Microstructure

  • AbstractIntroductionExperimental ProcedureResults and DiscussionConclusionsConflicts of InterestThis work addresses the influence of deformation temperature in a range from 40°C to 200°C on the microstructure evolution and mechanical properties of a low-carbon high-manganese austenitic steel. The temperature range was chosen to cope at the time during sheet processing or car crash events. Experimental results show that yield stress and ultimate tensile strength gradually deteriorate with an increase in the tensile testing temperature.

    Mechanical Properties and Failure Mechanism of the Polymer Composite with 3-Dimensionally Stitched Woven Fabric Macromol. Res., Vol. 11, No. 2, 2003 99 One layer of PU foam with closed pore structure was inserted in the sandwich structure and they were stitched by stitching yarns. The properties of materials used in this work are listed in Mechanical Properties and Failure Modes of Rock Specimens

    • AbstractIntroductionTesting SpecimensDescription of Laboratory TestExperimental MethodologyTesting Results and DiscussionFailure ModesDiscussions of Crack Force Analysis Based on Griffiths TheoryConclusionsData AvailabilityThe effects of disconnected joints on the mechanical characteristics of rock masses are interesting and challenging aspects of rock mechanics. The prime objective of this study is to investigate the effect of joint orientations and joint connectivity rates on the strength, deformation, and failure mechanisms of rock specimens under unloading condition. To establish the relationships between different factors (confining pressure, joint orientation, and joint connectivity) and failure mechanisms, a series of triaxial unloading tMechanical properties and failure mechanisms of closed Cell wall thickness variation leads to cell wall buckling and thus reduction in compressive and shear strengths of closed-cell foams. As cell size and cell wall thickness in foams become less

      Study on Mechanical Properties and Failure Mechanism of

      The mechanical properties of the components and the whole were obtained, and the related mechanical properties and failure mechanism of the materials were obtained. The main conclusions are as follows:(1) Under the action of tensile load, the fiber rod presents brittle fracture failure, and the failure section indicates that the fiber rod has The Effects of Strain Rates on Mechanical Properties and In this study, the effects of strain rates (from 0.001 s-1 to 400 s-1) on the mechanical properties and failure mechanism of LGFRPPs were investigated. The results showed that ultimate strength and fracture strain of the LGFRPPs increased obviously, whereas the stiffness remained essentially unchanged with the strain rates from low to high.
