## Description

- description: The evaluation of the R-curve behavior of ceramics, which is characterized
    by an increase in crack resistance with crack propagation, is crucial for advancing
    their implementation in engineering applications that require high reliability.
    In this study, we investigated the applicability of a finite element analysis
    (FEA) approach that implements a continuum damage model embedded with a cohesive-zone
    relationship to predict crack occurrence and the subsequent increase in crack
    resistance (toughness) of ceramics. Specifically, by employing a compliance-based
    method, the R-curve behavior was systematically examined under a bending load
    to assess the impacts of fracture stress and toughness on diverse chevron-notched
    specimens.
