The load-bearing properties and fracture patterns of structures made of concrete combined with rocks of varying properties exhibit notable differences. This study conducts experiments and numerical simulations on R-C central interface crack Brazilian disk specimens, investigating the effects of rock type, interface crack length, effective modulus ratio, and tensile strength ratio on fracture behavior under different loading angles. Quasi-static compression tests were carried out on sandstone-concrete (S-C) and granite-concrete (G-C) specimens at varying angles, revealing significant differences in fracture patterns and load-bearing capacity. The fracture patterns of S-C show interface extension cracks, tensile wing cracks, and vertical tensile cracks, while, G-C specimens exhibit additional single-wing crack patterns; Peak loads increase with loading angle, with G-C specimens initially having lower peak loads than S-C specimens at angles from 0° to 15°, but surpassing them at higher angles. Then, discrete element models of R-C were constructed using PFC2D and validated with experiments. The influence of interface crack length on the fracture patterns of S-C and G-C specimens was initially investigated using numerical methods. Subsequently, fracture propagation simulations for R-C samples with varying effective modulus and tensile strength ratios were performed. The simulation results show that smaller interface cracks lead to more secondary cracks in concrete, resulting in a heightened degree of fragmentation. Increasing effective modulus and tensile strength ratios result in various crack patterns: interface propagation crack, wing crack in rock and concrete, wing crack only in rock or concrete, vertical tensile crack in rock and concrete, and vertical crack only in rock or concrete; The peak load shows an increasing and then decreasing trend with increasing effective modulus ratio, while with the increase of tensile strength ratio exhibits an increasing and then steadily changing pattern.</div></div>","PeriodicalId":22879,"journal":{"name":"Theoretical and Applied Fracture Mechanics","volume":"134 ","pages":"Article 104757"},"PeriodicalIF":5.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical properties obtained from testing of small-scale tensile specimens were compared with results obtained from testing of specimens following ASTM E8 standard, to understand effect of specimen size on mechanical properties. Based on microstructural analysis, it was observed that below a VED value of 50 J/mm³, the conduction region prevailed, with the presence of irregular lack of fusion porosities. In VED range of 50–100 J/mm³, the transition prevailed with highly dense samples (over 99 % of theoretical density) with minimal porosity. Above a VED of 100 J/mm³, the keyhole regime prevailed with the presence of spherical keyhole porosities. STA heat treatment improved YS and UTS to ∼1200 and ∼1400 MPa, respectively, while reducing ductility to ∼15 %. HIP + STA had similar effect on tensile properties as STA heat treatment. Based on tensile strength data, it was observed that HIP is not essential for parts printed with optimum parameters.

However, the optimal fiber length and content considering various temperatures is still an unresolved issue in this field. To reach this goal, this research aims to study the impact of carbon fiber (CF) reinforcement on the fracture energy and toughness of AP under varying environmental conditions. Several mix designs considering different CF length (10–30 mm) and content (1–3.5 %) at 5 °C and ambient temperatures were evaluated to determine the optimal values. The results demonstrated that while increasing CF length and content generally improves fracture energy and toughness, there is an optimal threshold beyond which additional CF content yields diminishing returns. Notably, the sample with a 1.5 % replacement ratio and 15 mm CF length exhibited superior performance, significantly enhancing the AP’s resistance to fracture due to effective stress distribution and crack bridging. Conversely, samples with the higher fiber content and length showed decreased fracture toughness, due to fiber clustering and reduced workability. Additionally, experimental results indicated higher values at 5 °C for fracture energy and toughness. Advanced machine learning techniques were also utilized to develop predictive models to accurately simulate the fracture behavior of CF-reinforced AP mixtures. Among all models, Gaussian process regression demonstrated superior performance and exhibited lower error in predicting experimental data. Moreover, a sensitivity analysis of this model was conducted to determine how the length and content of CF, as well as temperature, influence fracture energy and toughness, guiding the optimization of CF integration in AP design.

It significantly reduces energy usage and minimizes carbon dioxide emissions, contributing to environmental sustainability. This study investigates the combined influence of granulated blast furnace slag, fly ash and silica fume on geopolymer concrete (GC) fracture resistance. This research aims to assess the fracture toughness of GC under modes I, III, and I/III loading conditions. Four distinct fiber types, comprising both short and long steel fibers and polypropylene fibers at 1.5 % dosage, were utilized to mitigate brittleness and enhance the ductility of the material. In addition, the microstructure of GC was analysed using X-ray diffraction and scanning electron microscopy. Findings reveal that the inclusion of short and long polypropylene fibers in GC increased mode I fracture toughness by 20.98 % and 29.62 %, respectively, compared to the fiber-free specimen, with long fiber showing superior performance due to its enhanced crack-bridging ability. Steel fibers provided a more pronounced improvement, with short and long fibers increasing mode I fracture toughness by 77.77 % and 109.87 %, respectively, attributed to their capacity to hinder crack propagation and enhance fracture toughness.

The interior rim crack did not propagate over the entire 50000 km distance. Cracks initiated from the two through-rim defects and propagated at a slow speed. Then, equivalent tests were conducted to investigate crack propagation behavior of the shattered rim. The crack growth rate increased with the increase of crack length for the specimen under tension–torsion loading, while that decreased with the increase of crack length for the specimens under pure-torsion and compression-tension loading. The crack propagation retardation is attributed to the compression and friction of the crack surfaces. Finally, a model was developed to describe crack propagation retardation in shattered rims. The effective stress intensity factor predicted by the model initially increases and then gradually decreases. The shattered rim has a critical size at different depths from the tread under constant amplitude load.

Marble samples with rock bridge length (RBL) of 10, 20, 30, and 40 mm were prefabricated as parallel pattern, and they are subjected to multi-level fatigue loading paths. Testing results show that the rock bridge between the fissures resists rock deformation and the terminal volumetric strain decreases with increasing RBL. In addition, the hysteresis energy density and damage evolution are influenced by the rock bridge length. The strain energy density development aligns with deformation pattern results. Deterioration in the rock bridge structure causes reduced capacity and higher energy consumption. More energy is required to drive damage progression and crack connectivity in rocks with a larger RBL. Ultimately, two hysteresis indices are introduced to characterize fatigue damage evolution.
