High performance lattice boltzmann method yield-stress calculations based on intravital images of clot formation in live mice
… risks. The ability to access hydrodynamics stresses at which thrombus structure is likely to embolize can provide insight into the thrombogenesis process. Interestingly, the viscoelastic behavior exhibited by the thrombus resembles that of a Bingham fluid - a material that behaves as a rigid …

An automated methodology for dynamic force analysis of adaptive spatial trusses
… in each member can be found, and the resulting stresses are calculated. The members are also checked for buckling using Euler buckling theory. The stress calculations are checked against experimental values and show good agreement for both static only and static and dynamic loading.

Application and analysis of stiffened side shell panel failure for naval patrol craft
… Each ship's background is discussed, and primary stress calculations are presented with design margins based on classification societies, along with an engineering analysis of the failures that occurred on each vessel. Internal and external factors for overall hull strength reduction are examined …

Computational stress analysis using finite volume methods
… Further research has been carried out to solve stress problems in multi-physics phenomena using a Computational Fluid Dynamics(CFD) frame-work. This approach has the advantage in that it uses the similarities between fluid and solid momentum equations to introduce some modifications in a CFD …

Thermal modeling for calculation of formation temperatures for deep water wells with chemical heat source
… for deep water wells. Altering the thermal stresses results in increased tangential stresses in the vicinity of the wellbore and therefore increases the fracture gradient. Thermal stresses can be increased through a controlled exothermic chemical reaction of certain salts which are coated …

Design optimization of advanced PWR SiC/SiC fuel cladding for enhanced tolerance of loss of coolant conditions
… of the monolith matrix and brittle fracture. Stress field in the cladding design is simulated by finite element analysis under service and shutdown conditions at both the core's middle height and at the end of the fuel rod. Stresses in the fuel region are driven by the thermal gradient that …
