Investigating the uniaxial compressive mechanics of graded polymer foams via in-situ synchrotron X-ray microtomography

Paolo Iaccarino, Clément Rey, Lorenzo Miele, Victor Okumko et autres

Graded polymer foams are emerging as transformative materials for structural applications, outperforming uniform foams due to their spatially tailored density and microstructural features. However, harnessing their full potential requires a deep understanding of how their macroscopic mechanical behavior relates to their complex …

Graded expanded beads of polypropylene

Fabrizio Errichiello, Daniele Tammaro, Norbert Reichlet, Ernesto Di Maio

Polypropylene foams are very popular as high-performance and economical cellular materials. We explored the feasibility of producing non-uniform foam structures using commercial polypropylene to enhance its mechanical properties compared to the uniform structures representing the benchmark foams. The gas sorption stage has …

Thermo-rheologically complex polymers: multiaxial constitutive modeling, numerical implementation and experimental validation

Paolo Iaccarino, Ernesto Di Maio, Andreï Constantinescu, Ferdinando Auricchio

We propose a simple multiaxial linear viscoelastic constitutive model to describe the behavior of thermo-rheologically complex polymers in both the time and frequency domains. The numerical implementation is discussed along with the parameter identification procedure. In particular, we propose a modification of …

Periodic cooking of eggs

Emilia Di Lorenzo, Francesca Romano, Lidia Ciriaco, Nunzia Iaccarino et autres

Egg cooks are challenged by the two-phase structure: albumen and yolk require two cooking temperatures. Separation or a compromise temperature to the detriment of food safety or taste preference are the options. In the present article, we find that it is possible …

Rheology in novel egg cooking methods

Emilia Di Lorenzo, Rossana Pasquino, Nino Grizzuti, Ernesto Di Maio

Heat-induced gelation of egg proteins, influenced by factors such as temperature and time, affects texture. This study compares three cooking methods—hard-boiling, sous vide, and periodic cooking—using rheological measurements to investigate the sol–gel transition and texture development in both egg phases. The goal …
