What is the importance of strain rate on structural response under blast load?
What is the importance of strain rate on structural response under blast load?
This and other issues are discussed in the recent paper from Stochino F. and Carta G.:
“SDOF models for reinforced concrete beams under impulsive loads accounting for strain rate effects”, DOI: 10.1016/j.nucengdes.2014.05.022, Nuclear Engineering and Design 276, (2014), 74-86.

Sustainable development means meeting current needs without sacrificing the ability of future generations to meet their own needs. Sustainable development also means that maintenance, and enhance the rational use of the natural resource base, the foundation supports the anti-ecological pressures and economic growth.

Plasticity integration: satisfaction of the consistency requirement
Dear all,
I am trying to formulate the return mapping algorithm with Hill48 yield condition, isotropic hardening law and flow rule referenced to Simo & Hughes (Computational Inelasticity).
In section 2.2.2.1, equation (2.2.9) expresses the Kuhn-Tucker complementarity conditions:
In addition to conditions (2.2.9), satisfies the consistency requirement:
Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study
Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study, International Journal of Plasticity 60 (2014) 71–86. Martensitic tetragonal-to-monoclinic transformation in zirconia is a ‘‘double-edged sword’’, enabling transformation toughening or shape memory effects in favorable cases, but also cracks and phase degradation in undesirable scenarios.
Numerical approximation of tangent moduli
In this study, we presented a numerically robust procedure to evaluate 4th order tangent moduli which are vital for acheiving quadratic convergence of global Newton-Raphson scheme.
In this study, the proposed method is verified for hyperelastic models alone. However, the same can be extended to other constitutive models.
