Full-field measurement techniques are now mature. As such, they have profoundly impacted
the experimental mechanics community in recent years. The way that shape memory alloys …

There is a growing body of evidence that “in situ” modification of the microstructure of Nitinol
due to pre-strain and mean strain strongly influence the fatigue properties of implanted …

The grain size (GS) dependence of fatigue crack growth in nanocrystalline superelastic NiTi
shape memory alloys (SMAs) with the average GS of 10, 30, 60 and 235 nm is investigated …

Computational modeling and simulation are commonly used during the development of
cardiovascular implants to predict peak strains and strain amplitudes and to estimate the …

We implement an approach using Bayesian inference and machine learning to calibrate the
material parameters of a constitutive model for the superelastic deformation of NiTi shape …

By choosing the dissipation energy as the damage variable, corresponding damage
evolution equations are established, respectively, for the mechanical cyclic loading part and …

Severe plastic deformation (SPD) has led to the discovery of ever stronger materials, either
by bulk modification or by surface deformation under sliding contact. These processes …

Shape memory alloys (SMAs) are those that can return to their initial shape after deformation
under a stimulus, such as temperature or stress. They are capable of recovering …

Nitinol is a shape memory alloy that has many applications in the biomedical, aerospace,
civil engineering, and automotive fields ranging from coronary stents to morphing wings on …

This doctoral thesis deals with the analysis of the role of stress risers in NiTi elements on the
local cyclic evolutions of martensitic transformation, plastic deformations, and mechanical …
