This material often contains bulk flaws; more so when for example waste cullet is used. A substantial obstacle to a wider application of such glass components is the lack of reliable methods for evaluating the effect of these bulk flaws on the mechanical performance of the material. Current standardized strength testing methods for glass focus on surface and edge characterization of thin, homogeneous elements.</p><h3>Objective</h3><p>This paper identifies existing destructive methods with potential for measuring the tensile strength of glass and other brittle materials; and assesses to what level they give information about the bulk strength in the presence of bulk flaws.</p><h3>Methods</h3><p>A literature review is conducted on existing destructive testing methods in use for brittle solids from various research domains and end applications.

The direct uniaxial tensile test is recommended for testing bulk flaws under a uniaxial tensile stress state, while the ultrasonic tensile test is discussed as a promising alternative.

Nevertheless, pure resins usually exhibit inherent limitations such as low modulus, poor wear resistance, and significant polymerization shrinkage. Adding inorganic fillers can effectively enhance the overall performances. However, the influence of filler content on the shrinkage stress evolution of the composites during photopolymerization remains controversial in previous studies.</p><h3>Objective</h3><p>This study aims to quantify the effect of the filler content on the shrinkage stress through combined theoretical prediction and experimental validation, and to further explore a quantitative criterion for resolving contradictions under varying constraints conditions.</p><h3>Methods</h3><p>Based on a previously developed mechano-chemo-thermo-coupled theory, we predicted shrinkage stress variations with filler content under systematically-varied constraint stiffness, which were verified by experiments using a self-built cantilever beam testing instrument.</p><h3>Results</h3><p>Experiments and predictions confirmed that the filler content and the constraint stiffness synergistically regulate shrinkage stress: with increasing filler content, shrinkage stress first increases and then decreases, while the peak stress does not necessarily fall within the typical 0–50 vol.% filler range. Key factors governing the peak shrinkage stress were identified as the constraint stiffness, the sample height, cross-sectional area, and the elastic modulus of the testing material. Based on these analyses, we proposed a quantitative method to determine the filler content corresponding to the maximum stress using the stiffness ratio <i>k</i>_<i>t</i> = <i>k</i> / <i>k</i>₀, where <i>k</i> is the instrument stiffness and <i>k</i>₀ represents the effective stiffness of the testing sample.</p><h3>Conclusion</h3><p>This experiment–theory-combined study clarifies inconsistent filler content-shrinkage stress trends reported previously. Furthermore, a quantitative criterion based on the stiffness ratio (<i>k</i> / <i>k</i>₀) is established to guide the selection of optimal filler content for reducing shrinkage stress and enhancing material performance in practices with varying constraint conditions.</p></div>","PeriodicalId":552,"journal":{"name":"Experimental Mechanics","volume":"66 9","pages":"1603 - 1617"},"PeriodicalIF":2.9,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149309605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
