A three-dimensional nonlinear thread formulation developed by the first two authors [1] has been extended in this paper for modeling and simulation of woven fabrics and fiber-reinforced composites of various configurations under arbitrary large deformation. The resultant model accounts for extensibility of the woven fibers in the composite, geometry nonlinearity, tension variation along the fiber, and other nonlinear effects due to the woven composition and large deformation. The new modeling effort includes the development of a contact model for simulating the contact between fibers, which can be used to predict high-fidelity behavior of woven fibers in the composite and their interactions. Matrix model is also added into the composite for studying the coupling between woven fibers and matrix material such as resin. The incremental form of original nonlinear equation is discretized using a finite element method with an iteration scheme. Two numerical examples are given to demonstrate the effectiveness of the proposed modeling technique.

Shear Panel

Recently, building and other civil engineering structures are built with energy dissipating device in order to reduce the damages caused by earthquake. There are a number of seismic energy dissipating device and steel dampers are among many energy dissipation device which is widely used because they are easy for construction, maintenance and low cost. Shear panel damper (SPD) is a type steel damper that dissipates energy by metallic deformation or using hysteresis of material as a source of energy dissipation. Low yield point steel is a good material to be used as a hysteresis damper since it has excellent ductility performance. Nonlinear finite element analysis was carried out to predict the large deformation and hysteretic behavior of SPD using low yield point steel (SLY120) for different width-to-thickness ratio. In order to verify the analysis simulation, quasi-static loading was also conducted and from the comparison a satisfactory result was found.

Kelvin Model

Considering the larger vibration amplitude and several viscoelastic material layers, a fractional-derivative Maxwell Kelvin (FDMK) viscoelastic mechanical model is proposed for “5+4” viscoelastic damping wall, which is used for vibration control of building structures. The development of the model is based on in-parallel combination of fractional Maxwell model and fractional Kelvin model. The proposed model is experimentally validated and very good agreement between predicted and experimental results was obtained. The results confirm that the FDMK model is accurate in simulating the hysteresis properties of the “5+4” viscoelastic damping wall under large deformation. From the areas of the experimental and theoretical hysteresis loops, under 300% strain, the predicted result is the most accurate in prediction of the energy dissipation and the second is the prediction under 450% strain. Moreover, from the comparisons of dynamic properties (storage modulus, loss modulus, etc.), the FDMK model works satisfactorily. The FDMK model is more sensitive in energy dissipation than in energy storage.

The Uniqueness Theorem

Thermoelastic equations without energy dissipation are formulated for a body which has previously received a large deformation and is at nonuniform temperature. A linear theory of thermoelasticity without energy dissipation for prestressed bodies is derived and the uniqueness theorem for a class of mixed initial-boundary value problems is established.
