    • It is an object to provide a stress history measurement method and a stress sensor by which the stress history of an object being measured can be measured easily with high accuracy over a wide stress measurement range. In the stress history measurement method, the stress history to which the object being measured has been subjected is measured on the basis of the ratio of twinned calcite particles after the object to be measured has been subjected to an external force, the object having a stress sensor embedded therein and capable of being deformed elastically when being subjected to the external force, the sensor including a number of calcite particles. The stress sensor is configured such that a number of calcite particles are hardened by a resin with adjacent particles kept in contact with each other.
    • 本发明的目的是提供一种应力历史测量方法和应力传感器,通过该应力传感器,可以在宽的应力测量范围内以高精度容易地测量被测量物体的应力历史。 在应力历史测量方法中,测量被测量物体的应力历史是基于被测量物体受到外力之后的孪晶方解石颗粒的比例进行测量的,物体具有应力 传感器嵌入其中并且当受到外力时能够弹性变形,传感器包括多个方解石颗粒。 应力传感器构造成使得多个方解石颗粒被相邻颗粒彼此接触的树脂硬化。
