Microstructural and mechanical response of fly ash–bentonite modified fiber-reinforced concrete under coupled sulfate attack and wet–dry cycles
Concrete infrastructures located in coastal areas are frequently subjected to coupled sulfate corrosion and wet–dry cycling (WDC). The durability behavior of concrete incorporating bentonite and fly ash (FA) was evaluated under the simultaneous influence of WDC. Concrete containing nine mixtures of…

A complete dynamical analysis of a discontinuously driven resonance circuit
Multistable systems with non-smooth dynamics provide serious challenges to the engineering design. Using a suite of standard numerical tools, our analysis of a canonical non-smooth system: a resonant circuit with an asymmetric cubic restoring force fed by a discontinuous square wave voltage, offers…
