Local loads analysis method

Method 2 utilizes the local load analysis developed by Bijlaard in the 1950s, which was further refined and described in the WRC Bulletin 107. This procedure uses the principles of flexible load surfaces. This procedure is more accurate, but more mathematically rigorous as well. 

Over equivalent local loading rate ranges, experiments with tensile type specimens using an FBA data reduction and experiments with bending type specimens using the DKC da a analysis method yield equivalent fracture toughness values. 

The following two examples [EINAX et al., 1990 KRIEG and EINAX, 1994] demonstrate not only the power, but also the limits of multivariate statistical methods applied to the description of polluted soils loaded with heavy metals from different origins. Case studies with chemometric description of soil pollution by organic compounds are also discussed in the literature. DING et al. [1992], for example, evaluated local sources of chlorobenzene congeners in soil samples by using different methods of multivariate statistical analysis. 

In any structure the entire structure responds to mechanical or thermal loads. It is also necessary to bear in mind that any structure will also experience localized stress concentrations at points of contact or separation in the structure. These points of contact or separation are sites susceptible to damage, cracking or failure initiation. Stress analysis using the finite element method in structures which are bolted, mating surfaces, vessels... 

The thermal system model for radiant-tube continuous furnace involves integration of the mathematical models of the furnace enclosure, the radiant tube, and the load. The furnace enclosure model calculates the heat transfer in the furnace, the furnace gas, and the refractory walls. The radiosity-based zonal method of analysis [159] is used to predict radiation heat exchange in the furnace enclosure. The radiant-tube model simulates the turbulent transport processes, the combustion of fuel and air, and the convective and radiative heat transfer from the combustion products to the tube wall in order to calculate the local radiant-tube wall and gas temperatures [192], Integration of the furnace-enclosure model and the radiant-tube model is achieved using the radiosity method [159]. Only the load model is outlined here. 

In our thermal analysis, the sedimentary blanket, the lithosphere, and the upper part of the asthenosphere are considered together. This approach allows us to calculate the amplitude of tectonic subsidence by considering changes in the density distribution vs. depth in the lithosphere. Local isostatic response of the lithosphere on load is assumed, and then the comparison of relative variations in the amplitude of tectonic subsidence is calculated by traditional methods (removal of the water and sediment load on the basement surface), with the variations obtained by nontraditional methods (consideration of changes in the density profile in the basement) providing an additional opportunity to control the program s sequence of the tectonic and thermal events in the lithosphere.
