Overall buckling and wrinkling of debonded sandwich beams under compressive loads were analyzed by both finite element and experimental methods.In the finite element method, a quarter and a half models of the specimens were analyzed.It shows that a quarter model is not adequate to analyze buckling of debonded sandwich beams, since it will disregard
A recent road cut through a Dammam Formation outcrop on the Dammam Dome in Dhahran, Saudi Arabia, exposed an array of open fractures and gypsum-filled veins.The discontinuities were mostly contained within the Saila Shale member and consisted of horizontal, vertical, and inclined extensional fractures, most of which were filled with gypsum.The vein
Structural fractures generally develop in the upper crust strata and are usually distributed in a convergent pattern, forming structural fracture zones with a specific strike.Fracture zones control the reservoir here seepage system and seriously affect the migration and accumulation of oil and gas in tight sandstone reservoirs.Therefore, characteri
Abstract Background In a broad variety of species, muscle contraction is controlled at the neuromuscular junction (NMJ), the peripheral synapse composed of a motor nerve terminal, a muscle specialization, and non-myelinating terminal Schwann cells.While peripheral nerve damage leads to successful NMJ reinnervation in animal models, muscle fiber rei
