Quantitative Classification

The rock mass quality classification method was introduced for the strength parameters and deformation parameters when carrying out quantitative classification and provided a theoretical basis; Introducing unloading rock mechanics theory, the infiltration conditions of the surface, drainage measures , catchment area as well as the subsequent impact of buildings on the slope were considered in order to increase the coverage of evaluation factors; Considering finite element analysis results of three-dimensional model and reference targets selected , one kind of improved numerical analysis method based on fuzzy - accurate evaluation of slope stability was proposed. The method is based on finite element model of the calculation results and the appropriate references selected, having the calculation analysis of certain factors on the slope stability a quantitative treatment, thus objectively established the weight ratio between these factors, avoiding subjective awareness in expert scoring impacting evaluation results too large. With practical engineering analysis it shows: the method is directed against rock slope analysis , make more factors impacting rock slope stability involved in evaluation, and easy to operate.

Behavior Characteristics

Recently, product manufacturers of mobile phone have to meet to high demands that allow their products endure variable bad environments exposed throughout the customers’ use. Especially, mobile phones need to resist to high humidity and general waterproofing that is prevalent in everyday usage. However, most previous studies related to seal material or methods for sealing assembly have been focused on heavy industry or automotive industry. In this paper, the aim is to predict waterproof possibility of mobile phone by using finite element analysis in design step. The criteria of waterproof condition for mobile phones was based on IEC60529 IPX-7 level[1]. This paper studied behavior characteristics and properties of the specialized rubber material for sealing the mobile phone housing. Constitutive equation for specialized seal rubber material was applied to the 3rd order Ogden function. Then, the correlation with test and finite element model was studied. Using the correlated finite element model for specialized seal rubber, evaluated behavior characteristics for seal rubber 2D shape and studied waterproof possibility analysis 3D model of mobile phone. The proposed suggestion is expected to predict waterproof possibility for mobile phone efficiently. Evaluation method of 2D finite element model will be useful for decision design specification of seal rubber shape at preceding design step. And evaluation method of 3D finite element model will predict waterproof possibility before tooling the mold and will save the costs at development step in industry.
