Sensitivity analysis of investigating the parameters effect on the effective width of stressed-skin panels with single-skin and double-rib is presented. Based on the results, a simple formula for predicting the effective width of stressed-skin panels was derived. With this formula, the effective width (ratio) of flange can be determined by multiplying the primary effective width ratio, which is...

Three-dimensional finite element modeling of residual stresses in a girth-welded pipe is presented in this paper, with an emphasis on modeling procedures for the global residual stress characteristics. The shell element model with a heat source moving along the circumferential joint is demonstrated to be cost effective and capable of predicting the global residual stress features. Transient res...

One of the most controversial issues in total knee replacement is whether or not to resurface the patella. In order to determine the effects of different designs of femoral component on the conformity of the patellofemoral joint, five different knee prostheses were investigated. These were Low Contact Stress, the Miller-Galante II, the NexGen, the Porous-Coated Anatomic, and the Total Condylar ...

The paper considers a set membership joint estimation of variables and parameters in complex dynamic networks based on parametric uncertain models and limited hard measurements. A recursive estimation algorithm with a moving measurement window is derived that is suitable for on-line network monitoring. The window allows stabilising the classic recursive estimation algorithm and significantly im...

To achieve the safety assurance of nuclear power plants, in-service inspection have were enforced periodic for nondestructive test in weldment. Among them, ultrasonic evaluation is widely used measurement defects. Generally, non-destructive inspectors calibrated a UT machine using reference specimen artificial cracks such as EDM, mechanical notch. As reflected signal real crack was detected amp...

The industrial process adds to engineering wood products features absent in solid wood, with homogeneous structure and reduced defects, improved physical and mechanical properties, bio-deterioration, resistance and better dimensional stability, improving quality and increasing the reliability of structures wood. These features combined with using fast-growing trees, make them environmentally ec...
