对圆柱压头的压痕蠕变和压痕疲劳进行了综述。对于印象蠕变，给出了不同情况下的解析解和计算机模拟。测试的材料包括金属和合金、超塑性材料、焊接件、玻璃、陶瓷和聚合物。用压痕技术测量粘度和薄膜的压痕蠕变也进行了讨论。对于压痕疲劳，每循环出现一个稳态，最大应力呈幂律关系。描述了欠载和过载效应以及延迟延迟。本文还简要讨论了其他局部测试，如纳米压痕、应力松弛、压痕恢复和由压痕测试确定的附着能。
Impression creep and impression fatigue, both using cylindrical indenters, are reviewed in this paper. For impression creep, analytical solutions and computer simulations for different situations are presented. Materials tested include metals and alloys, superplastic materials, weldments, glasses, ceramics and polymers. Viscosity measurements using indentation techniques and impression creep of thin films are discussed also. For impression fatigue, a steady state per cycle is shown and the power law dependence of maximum stress is presented. Underloading and overloading effects, as well as delayed retardation, are described. Other localized tests, such as nanoindentation, stress relaxation, impression recovery and the adhesion energy determined by impression testing, are briefly discussed also.
