Two-Dimensional Deformation Estimation of Beam-Like Structures Using Inverse Finite-Element Method: Theoretical Study and Experimental Validation

, 2021
The real-time estimation of structural deformations using discrete strain data, known as shape sensing, is critical to the health monitoring of structures such as bridges.

An inverse finite element method for pricing American options

Journal of Economic Dynamics and Control, 2013
Abstract The pricing of American options has been widely acknowledged as “a much more intriguing” problem in financial engineering. In this paper, a “convergency-proved” IFE (inverse finite element) approach is introduced to the field of financial engineering to price American options for the first time. Without involving any linearization process at

An inverse finite element method for the analysis of VIV data

Marine Structures, 2013
Abstract This paper presents an algorithm for the frequency domain solution of dynamic linear “inverse” problems, that is for the processing of measurement data (strain, acceleration etc.) acquired on a mechanical structure, in order to estimate the loads acting on the structure and its corresponding response.

Deformation Reconstruction for a Heavy-Duty Machine Column Through the Inverse Finite Element Method

IEEE Sensors Journal, 2020
The processing errors for columns of heavy-duty machine tools are affected by deformation induced by a variety of force loads and thermal loads. In general, error reduction usually uses method of error compensation.

A non‐iterative finite element method for inverse heat conduction problems

International Journal for Numerical Methods in Engineering, 2003
AbstractA non‐iterative, finite element‐based inverse method for estimating surface heat flux histories on thermally conducting bodies is developed. The technique, which accommodates both linear and non‐linear problems, and which sequentially minimizes the least squares error norm between corresponding sets of measured and computed temperatures, takes ...

Moore-penrose inverse method of topological variation of finite element systems

Computers & Structures, 1997
Abstract A topological modification method for structural variations of finite element system is studied in this paper. The Moore-Penrose (M-P) inverse theory and a new factorization of a stiffness matrix are used. A set of explicit formulations of variations are obtained.

Time-Domain Finite Element Method for Inverse Problem of Aircraft Maneuvers

Journal of Guidance, Control, and Dynamics, 1997
Summary: A method for solving nonlinear inverse problems is proposed. The inverse problem is formulated as a general optimization problem with equality constraints that are functions of state variables. The optimality conditions are derived by a variational approach.
