摘要

这一贡献涉及到一种新的剪切试样的发展，它允许对大剪切值进行精确的简单剪切测量。主要思想是橡胶垫的剪切载荷是通过钢销施加的。形式配合连接的优点是，对于负载应用，不需要夹紧力或高摩擦系数。此外，避免了由硫化或粘合引起的缺点，例如收缩。这提供了一个巨大的优势，即可以进行均匀老化测试，也可以测试纤维增强材料。为了展示新引脚设计的潜力，对仿真结果进行了比较，并进行了首次实验实现。这种新型剪切试样可用于橡胶性能的现象学研究，如Payne效应、Mullins效应、各向异性、永久凝固、软化、恢复、蠕变和松弛行为。

Development of a shear device for precise simple shear measurements of rubber mats

This contribution deals with the development of a new shear specimen, which allows precise simple shear measurements for large shear values. The main idea is that the shear load for the rubber mat is applied via steel pins. A form fit connection has the advantage that for the load application, no clamping force or high friction coefficient is required. In addition, the disadvantages resulting from vulcanisation or bonding, for example, shrinkage, are avoided. This offers the big advantage that homogeneous ageing tests can be performed, and also fibre‐reinforced materials can be tested. In order to show the potential of the new pin design, simulation results are compared to each other, and also a first experimental implementation is conducted. The new shear specimen can be used for phenomenological investigations of rubber properties, like Payne effect, Mullins effect, anisotropy, permanent set, softening, recovery, creep and relaxation behaviour.

期刊介绍： Strain is an international journal that contains contributions from leading-edge research on the measurement of the mechanical behaviour of structures and systems. Strain only accepts contributions with sufficient novelty in the design, implementation, and/or validation of experimental methodologies to characterize materials, structures, and systems; i.e. contributions that are limited to the application of established methodologies are outside of the scope of the journal. The journal includes papers from all engineering disciplines that deal with material behaviour and degradation under load, structural design and measurement techniques. Although the thrust of the journal is experimental, numerical simulations and validation are included in the coverage. Strain welcomes papers that deal with novel work in the following areas: experimental techniques non-destructive evaluation techniques numerical analysis, simulation and validation residual stress measurement techniques design of composite structures and components impact behaviour of materials and structures signal and image processing transducer and sensor design structural health monitoring biomechanics extreme environment micro- and nano-scale testing method.
