Damage of a 5-story framed structure was identified from two types of measured data, which are frequency response functions (FRF) and natural frequencies, using a finite element (FE) model updating procedure. In this study, a procedure to determine the appropriate weightings for different groups of observations was proposed. In addition, a modified frame element which included rotational spring...

in this paper, a three-dimensional finite element model has been developed to simulate the laser-tig hybrid welding (hlaw) of stainless steel 1.4418 with thickness of 4 mm. transient temperature profile and dimensions of the fusion zone and heat affected zone (haz) during welding process are calculatedusing finite element method (fem) and were solved in the abaqus/standard software.the heat sou...

this research work is devoted to the footprint analysis of a steel-belted radial tyre (185/65r14) under vertical static load using finite element method. two models have been developed in which in the first model the tread patterns were replaced by simple ribs while the second model was consisted of details of the tread blocks. linear elastic and hyper elastic (arruda-boyce) material models wer...

latticed columns are frequently used in industrial steel structures. in some countries these built-up columns might be even used in other types of steel structures such as residential and commercial buildings. besides, latticed columns are parts of skeletons of many historic buildings all around the world. to analyze a steel structure with latticed columns a more accurate numerical model for su...

1 INTRODUCTION Dozens of finite element model updating methods have been studied and suggested but still it remains as a difficult problem. That is because model updating is an inverse process and often contains highly non-linear characteristics. Also the updated result is not unique and depends heavily on the objective function and parameters used in the updating process. Usually, objective fu...

We present a finite element model updating technique for soil–structure system identification of the Millikan Library building using seismic data recorded during 2002 Yorba Linda earthquake. A detailed (FE) is developed in OpenSees and updated sequential Bayesian estimation approach joint parameter input identification. two-step devised. First, fixed-base structural to estimate parameters (incl...

Finite element model updating utilizing frequency response functions as inputs is an important procedure in structural analysis, design and control. This paper presents a highly efficient framework that built upon Gaussian process emulation to inversely identify parameters through sampling. In particular, multi-response (MRGP) meta-modeling approach formulated can accurately construct the error...

This work presents a numerical approach in order to predict the influence of implant material stiffness in a femoral component design when submitted in compression. The implant success depends on the transferred load to the neighboring bone. The finite element method can be used to analysis the stress and strain distribution in the femoral component allowing to improve the implant selection. Fo...
