Linking parameters between structural performance and service performance can be established by linking the physical parameters and the mechanical and electrical properties of materials. In this study, we applied the Probabilistic Neural Network (PNN) based on a concept of expectation-value, to correlate the creep parameters of metals with their improvement efficiency. To this end, we selected five creep-simulating parameters and two thermodynamic-based screening aspects of materials.
Identifying the occurrence of defects (cracks, delamination, etc.) in large structures as efficiently as for small structures is essential not only for seismic-resisting civil engineering, but also in the planning and cost management of large structures. In this study, we adopted a K-fold cross validation method using structural components, and carried out quantitative analysis of helical strip communities obtained by non-destructive examination. The experimental results indicated that the detection capability of the proposed method for large structures was confirmed.
The main aim of this research is to investigate the feasibility of creating a prototype vehicle model and verify the reliability. An experimental procedure is presented for three methods: a method using numerical analysis, a method using physical analysis and a method using a prototype vehicle. An analysis of results obtained with each of the three methods is made, and the conclusion is that these methods are feasible in order to design and develop a prototype vehicle.
In this research, a full statistics of a bearing is carried out by the finite element method (FEM). A full-scale experimental test was conducted to check the validity of this method, in which the test results are qualitatively and quantitatively compared with those from other research. The comparison indicated that this method is valid for the bearing.
This study aims to establish a mechanics-based model and calculate the contact pressure of steel plates in soft soil including rocks by a finite element method (FEM). The research results show that the contact area decreases by increasing the contact pressure and that the experimental results are in agreement with the model results owing to the precision of measurement. d2c66b5586
