Heater Tube

A new type of laminar composite material has been developed by the bonding of ceramic and metal with a special agglutinate metal. A tube can be made of the laminar composite material and this tube can perform as an outer sheath of an immersion heater. Such heaters can be made to lager size and can be heated using a wide range of energy sources including electricity, gas and oil. Moreover this new heater tube is low cost and has a long working life, is convenient to use and requires little maintenance. This technology allows all kinds of zinc kettle to be heated by immersion heaters.

Fiberglass Composite

A stress state of the partially damaged underground steel pipeline after reconstruction by means of the fiberglass composite material is considered. The strength properties of the composite are determined experimentally. The effective elastic moduli of the composite are determined by means of the finite element homogenization. Tsai-Wu failure criterion is used for the composite part of the pipeline. The influence of geometrical parameters and loading conditions on the safety factor of the pipeline is analyzed and discussed.

Application Fields

Shape memory alloy (SMA) has various application fields due to its shape memory effect and super elasticity. It can also be embedded into other material to produce SMA reinforced composite (SMAC). SMAC is a good candidate to realize structural smart control. In this paper the mechanical properties of SMAC in the plane stress state is investigated based on the theory of mechanics of composite material and the constitutive model expressing the thermo-mechanical behaviors of SMA.

Finite element simulations of three laminates in open-hole and unnotched configurations subjected to tension and compression quasi-static loading are investigated as part of the Damage Tolerant Design Principles program organized by the Air Force Research Laboratory. The coupons are made from unidirectional IM7/977-3 plies, which are a composite material composed of intermediate modulus carbon fibers and a toughened epoxy matrix. Blind simulations of coupon stiffness, nominal coupon stress at failure and damage evolution are benchmarked against experimental measurements and X-rays. The blind simulations are followed by a second round of simulations where the modeling strategy is modified to improve agreement between the simulations and experiments. In the present article, the commercial software Autodesk Helius PFA is used to model the non-linear response of the composite material. Within Helius PFA, failure is evaluated at the constituent level by extracting the fiber and matrix volume average stress state from the homogenized composite stress state. The relationships between the composite and constituents are developed using multicontinuum theory and a high-fidelity micromechanics model.

The stress-strain state of impeller seal made ​​of composite material a centrifugal pump under the thermal effects is investigated based on the classical theory of elasticity of an anisotropic body. Kinematic and static conditions of contact for mating surfaces of adjacent layers are considered ideal. Solution of the problem is obtained in axisymmetric. It is noted that the increase in temperature on the surface of the composite seal has a significant impact on its stress state.
