Three Dimensional Finite Element

A three-dimensional finite-element simulation study, developed for the purpose of modeling the event of a compact automobile impacting a modified thrie-beam guardrail, is presented. The developed computational model has been used to simulate an actual field test that was previously conducted as part of a full-scale crash test program carried out under the auspices of FHWA. Results of the actual crash test are also used to "tune" the simulation model.

This paper adopts general finite element software to carry out three-dimensional finite element simulation analysis for Huizeli reinforced concrete rectangular-sectioned aqueduct. Considering four combination cases in aqueduct’s construction and operating process, researching variation laws of the aqueduct’s stress and displacement. Analysis results show that design scheme of Huizeli reinforced concrete rectangular-sectioned aqueduct is reasonable, it can meet design requirements. Analysis results provide some theory references for design of reinforced concrete rectangular-sectioned aqueduct.
