Rate and thermal sensitivities of unstable transformation behavior in a shape memory alloy (2004, methodology): “M (loading) transformation (Shaw, 2000).”
A finite strain kinematic hardening constitutive model based on Hencky strain: General framework, solution algorithm and application to shape memory alloys (2011, background): “In most applications, SMAs experience complicated multi-axial loadings, typically undergoing very large rotations and moderate strains (i.e., in the range of 10–15% for polycrystals Shaw, 2000).”
Rate-dependent domain spacing in a stretched NiTi strip (2010, methodology): “Based on the above scenario of thermo-mechanical coupling, computational studies were performed (Shaw and Kyriakides, 1998; Shaw, 2000; Iadicola and Shaw, 2004) and important insight into the multiple-domain formations has been obtained.”
