A numerical compaction model of overpressuring in shales
A one-dimensional, numerical model of sediment compaction has been developed using porosity, velocity of sediment particles, and depth of the evolving basin as master variables. The governing set of nonlinear, partial differential equations are solved by a finite difference scheme devised to be …

Modeling, Analysis, and Experiments of Inter Fiber Yarn Compaction Effects in Braided Composite Actuators
… has a high bulk modulus. Several analytical models have been previously developed that capture the geometrical and material nonlinearities, the compliance of the inner liner, and entrapped air in the fluid. The inter fiber yarn compaction in the fiber layer, which is shown to reduce the …

Digital Simulation of Compaction in Sedimentary Sequences
A compaction model which incorporates energy transport with fluid flow to investigate the role of three-dimensional loading and thermal expansion of fluid in generating the excess pore pressure in nonhomogeneous sedimentary sequences is developed. In this model, physical properties of fluid and …

Fiber compaction and wetout in tapered resin injection pultrusion manufacturing
… of this research is to present a numerical model employing the finite volume technique to simulate the resin flow in a tapered injection chamber through the fiber reinforcement when compaction of the fiber reinforcement is taken into account. The numerical model predicts the impact of design …

A model of the winding and curing processes for filament wound composites
… investigation was to develop a two-dimensional model which describes the winding and curing processes of filament wound composite structures. The model was developed in two parts. The first part is the cure model which relates the cure temperature, applied at the boundaries of the composite, to …

Vacuum Assisted Resin Transfer Molding (VARTM): Model Development and Verification
… Transfer Molding (VARTM) process simulation model was developed and verified. The model incorporates resin flow through the preform, compaction and relaxation of the preform, and viscosity and cure kinetics of the resin. The computer model can be used to analyze the resin flow details, track …

Shock compression and dynamic fragmentation of geological materials
… which was analysed using geometric grain models and Hertzian contact theory. The shock Hugoniot of each ma- terial was measured though a series of plate impact experiments using a light gas gun. The experiments focused on the stress region of interest for blast mining, 0 to 12 GPa. The, …

Hot spots in ammonium nitrate
… the form of grains roughly 50 μm in size. The compaction behaviour of confined cylindrical beds of these prills and pellets was studied at strain rates between 4 × 10−4 s−1 and 200 s−1. Quasi-static experiments were performed using a screw-driven instrumented press, while higher-rate …
