Isogeometric analysis of linear isotropic and kinematic hardening elastoplasticity

Vietnam Journal of Mechanics, 2017
Material nonlinearity is of great importance in many engineering problems. In this paper, we exploit NURBS-based isogeometric approach in solving materially nonlinear problems, i.e. elastoplastic problems.

A strategy to improve the work-hardening behavior of Ti–6Al–4V parts produced by additive manufacturing

Materials Research Letters, 2017
To improve the mechanical properties of additively manufactured parts, specific heat treatments must be developed. Annealing of electron beam-melted Ti–6Al–4V was performed at sub-transus temperatures and followed by water quenching.
