A microscale second gradient approximation of the damage parameter of quasi-brittle heterogeneous lattices
Antonio Rinaldi,Luca Placidi +1 more
TL;DR: In this article, the authors explore the connection between the series of critical strains at which the microcracks form and the second gradient of the microscale displacement field and support the new view that the damage evolution is a three regimes process (I dilute damage, II homogeneous interaction, III localization).

TL;DR: In this article, the authors describe an approach to incorporate the effects of granularity in monolithic cementitious materials, which is known to be significantly affected by their granular nature.

Thermomechanics-based nonlinear rate-dependent coupled damage-plasticity granular micromechanics model
Anil Misra,Viraj Singh +1 more
TL;DR: In this article, a general thermomechanical framework applicable to rate-dependent granular materials with damage and plasticity is developed, and an expression for macro-scale Cauchy stress tensor is obtained in terms of the micro-scale grain interaction forces and the relationship between micro- and macroscale kinematics.

On materially and geometrically non-linear analysis of reinforced concrete planar frames
TL;DR: In this article, a family of new beam finite elements for geometrically and materially nonlinear static analysis of reinforced concrete planar frames is derived, in which strain measures are only interpolated unknowns, and where the constitutive and equilibrium internal forces are equal at integration points.
