[1] A size effect law for fracture triggering in dry snow slabs of high enough length-tothickness ratio is formulated, based on simplified one-dimensional analysis by equivalent linear elastic fracture mechanics. Viscoelastic effects during fracture are neglected. The derived law, which is analogous to Bažant’s energetic size effect law developed for concrete and later for sea ice, fiber compos...

Based on the engineering background of water dissolving mining for hydrocarbon storage in multi-laminated salt stratum, the mixed mode fracture toughness and fracture trajectory of gypsum interlayers soaked in half-saturated brine at various temperatures (20°C, 50°C and 80°C) were studied by using CSNBD (centrally straight-notched Brazilian disc) specimens with required inclination angles (0°, ...

Clayey tills contaminated with chlorinated solvents are a threat to groundwater and are difficult to remediate. A numerical model is developed for assessing leaching processes and for simulating the remediation via enhanced anaerobic dechlorination. The model simulates the transport of a contaminant in a single fracture-clay matrix system coupled with a reactive model for anaerobic dechlorinati...

This review paper discusses the basic problems related to use of cohesive models simulate initiation and development failure in various types engineering issues. The most commonly used zone (CZMs) are described. Recent achievements field modeling characterized, with particular emphasis on problem mixed mode loading, influence strain rate, stress state triaxiality, fatigue. A separate chapter wo...

SP interpretation can be ambiguous giving highly non-unique physical models. The ambiguity can be limited by constraining the interpretation. If the SP anomaly arises from forced convection along a vertical fracture zone, an integral equation can be derived from which the SP anomaly may be calculated or inverted to a source. The source arises from divergence of a product of flow parameters, div...
