This paper investigates the effect of porous microstructure on necking formability ductile sheets subjected to dynamic in-plane stretching. We have developed an original approach in which finite element calculations include actual void distributions obtained from additively manufactured materials are compared with simulations specimen is modeled Gurson–Tvergaard continuum plasticity theory (Gur...

This paper demonstrates that in the presence of indomethacin, a cyclooxygenase inhibitor, 100% of the mice died when infected with live Listeria, whereas none of the animals died in the absence of the drug. The death of the animals correlated with the numbers of bacteria found extraperitoneally in the spleen and not with the Ia expression of the peritoneal macrophages. Increases in the spleen b...

Abstract: In this paper, we discuss the similarity between two trajectories using Needleman Wunsch algorithm. The calculation steps are interpolating trajectory, calculating distance trajectory coordinates, identifying equivalent length, transforming into a sequence of alphabetic letters, aligning sequences, and measuring magnitude based on alignment results. obtained is compared directly to le...

Relations between fracture toughness and microstructural details have been calculated for ductile materials based on a dilatational plasticity constitutive model that has recently been proposed. The model generalizes the Gurson model to account for both void growth and coalescence with explicit dependence on void shape and distribution effects. Based on a small scale yielding formulation of cra...

An essential step in assessing and analysing the relationship between two or more proteins is the establishment of an alignment of their amino acid sequences. The prediction of an unknown protein structure by model building from the known structure of a homologue also requires the correct correspondence between the residues. Using sequence information alone, the optimal alignment determined by ...
