This paper presents a finite layer procedure for the consolidation analysis of layered soils using a cross isotropic elastic constitutive model. The program is first verified using two published results. Then using this program, the influences of cross isotropy on the consolidation behavior are analyzed. The results obtained using the cross isotropic elastic model are compared with results using isotropic elastic model. It is found that the cross isotropy has very large influences on the consolidation behavior. Curves of the average degree of consolidation are obtained and presented in the paper, which is useful for engineering practice.

Optimal slot dimension for skirt support structure of coke drums

The skirt-to-shell junction weld on coke drums is susceptible to fatigue failure due to severe thermal cyclic stresses. One method to decrease junction stress is to add slots near the top of the skirt, thereby reducing the local stiffness close to the weld. The most common skirt slot design is thin relative to its circumferential spacing. A new slot design, which is significantly wider, is proposed. In this study, thermal-mechanical elastoplastic 3-D finite element models of coke drums are created to analyze the effect of different skirt designs on the stress/strain field near the shell-to-skirt junction weld, as well as any other critical stress locations in the overall skirt design. The results confirm that the inclusion of the conventional slot design effectively reduces stress in the junction weld. However, it has also been found that the critical stress location migrates from the shell-to-skirt junction weld to the slot ends. A method is used to estimate the fatigue life near the critical areas of each skirt slot design. It is found that wider skirt slots provide a significant improvement on fatigue life in the weld and slot area.

In order to gain a deeper understanding of the significance of the Chinese Academy of Engineering's "China Intelligent Manufacturing Development Strategy Research Report Based on the New Generation of Artificial Intelligence", the author adopts the method of deconstruction and reconstruction, to analyze the Reference Architecture Model of Industrial 4.0 (RAMI 4.0) of Germany, and compared with the general architecture of intelligent manufacturing proposed in the report of the Chinese Academy of Engineering, and similarities and differences of each other are found. It is believed that the general architecture of the intelligent manufacturing in China is superior in intelligence. This is the Chinese contribution to the development of intelligent manufacturing. At the same time, the analysis deepens the understanding of the both architectures.

The concentration and components of manure phosphorus (P) are key factors determining potential P bioavailability and runoff. The distribution of P forms in swine, poultry and cattle manures collected from intensive and extensive production systems in several areas of China was investigated with sequential fractionation and a simplified two-step (NaHCO -NaOH/EDTA) procedures. The mean total P concentration, determined by the sequential fractionation procedure of intensive swine, poultry and cattle manure, expressed as g·kg , was 14.9, 13.4 and 5.8 g·kg , respectively, and 4.4 g·kg in extensive cattle manure. In intensive swine, poultry and cattle manure about 73%, 74% and 79% of total P, respectively, was bioavailable (i.e., P extracted by H O and NaHCO ) and 78% in extensive cattle manure. The results indicated the relative environmental risk, from high to low, of swine, poultry and cattle manure. There is considerable regional variation in animal manure P across China, which needs to be considered when developing manure management strategies.
