    • A pipe testing apparatus includes a mandrel adapted for insertion within the pipe and two sealing devices connected to the mandrel and adapted to seal opposite ends of the pipe to create an annular space between the mandrel, the pipe, and the sealing devices. The apparatus further includes one or more ports for filling the annular space with a pressurized fluid and a pressure gauge for monitoring the pressure within the annular space. At least one of the sealing devices includes a combination of a sealing ring and a force applying ring) which forces the sealing ring to bear against one end of the pipe to from a seal. The mandrel is provided with stops for preventing the at least one sealing device from moving axially away from the pipe.

    • A material test specimen design is taught for the determination of criticaltrain and stress states for multiaxial fracture. The objective of the specimen is to increase the amount of data obtained per specimen while retaining simplicity in testing procedure by using standard tension testing machines to generate the primary deformation of the specimen. The specimen, in conjunction with analytical or computational simulation, uses nonuniform deformation fields produced by secondary and tertiary strain concentrations to generate and track these multiaxial strain states to fracture. Typically, the primary deformation is uniaxial tension of a panel, the secondary strain concentration is a circular hole in the panel and the tertiary strain concentrations are areas of reduced thickness within the deformation field of the circular hole. Multiaxial strain ratios from -0.50 to -0.10 and control over fracture initiation sites may be generated by a test specimen design of the type taught by this invention.
    • 教授材料试样设计用于确定多轴断裂的临界应变和应力状态。 样本的目标是增加每个样本获得的数据量,同时通过使用标准拉伸试验机来保持试样的初步变形,从而保持测试过程的简单性。 样本与分析或计算模拟结合使用由二次和三次应变浓度产生的不均匀变形场,以产生和跟踪这些多轴应变状态进行断裂。 通常,主变形是面板的单轴张力,二次应变集中在面板中为圆形孔,第三应变浓度为圆孔变形场内厚度减小的区域。 通过本发明教导的类型的试样设计可以产生从-0.50到-0.10的多轴应变比和对断裂起始位置的控制。
