Hi,



I am using the VCCT method to model crack propagation and I am finding the value of G/Gc is too large for any sensible time step (1e-25).



I am attempting to incorporate a time incrementation scheme into my UMAT which monitors EFENRRTR and modifies the time step (or PNEWDT) according to it's value.

Nonlinear vibration of a nanoplate embedded on a Pasternak-type foundation using nonlocal continuum theory

Abstract:

Nonlocal plate continuum model is utilized to investigate the nonlinear vibration behaviour of a singlelayer

nanoplate. The isotropic nanoplate is assumed to be embedded on a Pasternak-type elastic foundation with the

The paper by Carta G. and Stochino F. presents two alternative approaches for the study of reinforced concrete beams under blast loads. In the first approach, the beam is modeled by means of Euler–Bernoulli’s theory and its elastic–plastic behavior is expressed through a new nonlinear relationship between bending moment and curvature. In the second approach, instead, the beam is idealized as a single degree of freedom system.
