Damage localization in truss girders by an application of the discrete wavelet transform [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023 The paper demonstrates the potential of wavelet transform in a discrete form for structural damage localization. The efficiency of the method is tested through a series of numerical examples, where the real flat truss girder is simulated by a ...

Analysis of high velocity impacts of quasibrittle material fragments with a Hopkinson bar [PDF]
EPJ Web of Conferences, 2021 In this work it has been characterized the impact behaviour of quasibrittle fragments against a Hopkinson bar in a wide range of impact velocities (70-180 m/s). Hopkinson bar is designed to measure the impact forces thanks to a proper instrumentation. In

Experimental analysis of high velocity impacts of composite fragments on aluminium plates [PDF]
EPJ Web of Conferences, 2021 The improvement of engines is one of the ways to diminish the fuel consumption in civil aircrafts, and Open Rotors engines are one of the best promises in order to achieve a sensible efficiency increment.

Hyperelastic Geometrically Nonlinear Inverse 3D-FEM Truss Analyses Based on VaReS
Advances in Civil Engineering, 2022 Direct usage of construction plans as input for structural analyses assumes the reference configuration to match the engineering drawings. However, the built construction is typically supposed to match the construction plans after its successful erection.

Finite element method-enhanced neural network for forward and inverse problems
Advanced Modeling and Simulation in Engineering Sciences, 2023 We introduce a novel hybrid methodology that combines classical finite element methods (FEM) with neural networks to create a well-performing and generalizable surrogate model for forward and inverse problems. The residual from finite element methods and
