Strain Hardening cementitious composites (SHCCs) have been known to produce excellent crack width control and very good tensile strain capacity. As a result, strategically introducing SHCCs would lead to significant carbon saving through the creation of structures that are durable and could potentially undergo autogenous self-healing. However, for wider acceptability of any new material requires long term empirical data. This may be circumvented by continually ensuring a structure made with this new material is serviceable i.e. material has not failed. We present an approach to predict failure time without any prior information on operating conditions and material information for SHCCs. This method is based on the modeling of ‘finite time singularity’ based on mathematical laws. The method produces fairly accurate results when applied to estimate failure for SHCCs with a wide range of failure times and to both linear and non-linear loading regimes. The practical applicability of this method was thus demonstrated.

众所周知，应变硬化水泥基复合材料（SHCC）具有出色的裂缝宽度控制和非常好的拉伸应变能力。结果，战略性地引入SHCC将通过创建耐用的结构并可能进行自发自愈的结构来显着节省碳。但是，要想使任何新材料具有更广泛的接受性，就需要长期的经验数据。可以通过持续确保用这种新材料制成的结构可以使用（即材料没有失效）来避免这种情况。我们提出了一种预测故障时间的方法，而没有关于SHCC的运行条件和材料信息的任何先前信息。该方法基于基于数学定律的“有限时间奇异性”建模。当该方法用于评估具有广泛故障时间的SHCC的故障以及线性和非线性加载方式时，该方法都能产生相当准确的结果。因此证明了该方法的实际适用性。
