Bending test apparatus and method for flexible sheet material
The present invention discloses a bending test apparatus and method for a flexible sheet material. The apparatus comprises a mounting table and further comprises a clamping unit and a bending shaft unit. The clamping unit comprises a clamping part. The bending shaft unit comprises a bending shaft extending in a Z-axis direction. The bending shaft has an arc-shaped sidewall for abutting against a flexible sheet material at an end thereof away from the clamping part. The clamping part moves relative to the bending shaft in a Y-axis direction. The present invention has the following advantage: During a test, a flexible sheet material is bent with a lower external strain, has a wide adjustment curvature range, and the structure is optimized.
Double-cross composite fabric membrane biaxial tensile strength test piece and manufacturing method thereof
A double-cross composite fabric membrane biaxial tensile strength test piece is provided, including a core region and four cantilevers. The four cantilevers extend outwards around the core region and form a cross shape. Each cantilever is connected to the core region via an edge transition region. An end portion of the cantilever is a clamping section. The clamping section is provided with a clamping end rubber rod. The clamping end rubber rod is used for connecting to a clamp of a biaxial tensile testing machine. The clamping section is three-layered. The cantilever and the edge transition region are double-layered. The core region is single-layered. The edge transition region is in the shape of a quadrangle rounded at four corners. A manufacturing method of the test piece is also provided.

The present invention relates to a plate-shaped chemically-strengthened glass which has a compressive stress layer provided to a glass surface layer, a glass surface hydrogen concentration profile in a specific range, and a surface strength and abrasion-resistant anti-fingerprint (AFP) properties which are in specific ranges.
High-throughput testing system and method for additive manufacturing
A method of testing a multi-specimen additive manufacturing build plate includes acquiring and installing the multi-specimen build plate in a test system, aligning one or more force exertion tools with respective selected specimens, imparting a force on the selected specimen(s), collecting test data from each selected specimen, and analyzing the collected data to identify a potential correlation between material behavior for the selected specimen and its applied manufacturing build parameter(s). A system and a non-transitory medium are also disclosed.
Method of estimating material properties of an elastic plate
A method is provided for increasing accuracy in measuring complex Young's modulus and complex shear modulus of a material using a processing system. The material is tested to obtain an experimental frequency response transfer function of normal displacement to input force. A model panel is developed in the processing system as a modeled frequency response transfer function. The modeled transfer function is used at a range of fixed frequencies to calculate displacements of the model panel divided by the input force while varying material parameters. The modeled frequency response transfer function is compared with the experimental frequency response transfer function to compute error function values. These values indicate the most accurate material property values as those minimizing the computed error function values.
