Modalno posodabljanje s pomočjo hitre kamere
Klemen Zaletelj, Janko Slavič, Miha Boltežar
Magistrsko delo
Oznake: magistrska dela;modalno posodabljanje;hitra kamera;strukturna dinamika;optični tok;iterativne metode;direktne metode;
Modalno posodabljanje z uporabo pospeškomerov je relativno dobro raziskano, a je merjenje velikega števila prostostnih stopenj lahko zamudno in včasih nemogoče. Hitra kamera omogoča merjenje velikega števila prostostnih stopenj hkrati, zato je tak pristop primeren za uporabo v postopku posodabljanja ...

Full-field DIC-based model updating for localized parameter identification
Klemen Zaletelj, Janko Slavič, Miha Boltežar
Izvirni znanstveni članek
Oznake: full-field response;digital image correlation;finite-element-model updating;localized parameters;
Identifying the local properties of a structure, either to perform structural health monitoringor to fine tune a numerical model, requires the updating of a large number of parameters.With a high spatial density, but a low dynamic range response information, high-speed-camerameasurements have the po ...

Uporaba hitre kamere za modelno posodabljanje v strukturni dinamiki
Klemen Zaletelj, Janko Slavič, Miha Boltežar
Doktorska disertacija
Oznake: disertacije;modelno posodabljanje;hitre kamere;naključni vzorec;lokacijsko uteženje;avtomatska parametrizacija;3D laserske oblike;
Cilj doktorske naloge je uporabiti visoko prostorsko ločljivost lastnih oblik, ki so na voljo pri meritvi s hitro kamero, za učinkovito in zanesljivo posodabljanje vedno bolj geometrijsko kompleksnih numeričnih modelov. Tekom doktorskega dela so potekale raziskave za generacijo naključnega vzora na ...

Application of thermoelasticity in the frequency-domain multiaxial vibration-fatigue criterion
Jaša Šonc, Klemen Zaletelj, Janko Slavič
Izvirni znanstveni članek
Oznake: thermoelasticity;multiaxial criterion;vibration fatigue;modal decomposition;
In vibration fatigue, high-spatial-density experimental damage identification is hard to conduct. Fatigue damage is typically localized (in time and space) and loads can change direction with time. Thermoelasticity studies the interaction between temperature changes and elastic deformations in mater ...

Multi-level curvature-based parametrization and model updating using a 3D full-field response
Klemen Zaletelj, Domen Gorjup, Janko Slavič, Miha Boltežar
Izvirni znanstveni članek
Oznake: FE model updating;interior point method;curvature-based parametrization;frequency-domain triangulation;
Model updating improves the correlation between the response of the real structure and the response of the finite-element (FE) model; however, the selection of the updating parameters (parametrization) is crucial for its success. Using full-field modal shapes, a large number of parameters can be upd ...

Strain experimental modal analysis of an Euler–Bernoulli beam based on the thermoelastic principle
Klemen Zaletelj, Janko Slavič, Jaša Šonc, Miha Boltežar
Izvirni znanstveni članek
Oznake: princip termoelastičnosti;deformacijske lastne oblike;modalna identifikacija;strukturna dinamika;thermoelastic principle;strain shapes;modal identification;structural dynamics;
The strain mode shapes can be utilized as an indicator of vibration fatigue-hotspots and are utilized for predicting the distribution of damage intensity. However, the conventional approach for measurement, which involves using strain sensors, does not offer the necessary high spatial density requir ...

Laser-light speckle formation for deflection-shape identification using digital image correlation
Klemen Zaletelj, Vid Agrež, Janko Slavič, Rok Petkovšek, Miha Boltežar
Izvirni znanstveni članek
Oznake: laser speckle;paint speckle;digital image correlation (DIC);full-field vibration identification;
The application of a speckle pattern to the surface of a structure is usually required for Digital Image Correlation (DIC)-based displacement identification. A speckle pattern generally requires the modification (e.g., painting) of the structure's surface. An improved method of laser-light speckle f ...
