Brittle failure in Abaqus

Submitted by surot on

Hi there,

Can anyone explain me the results I got from Explicit? I am investigating cracks propagation in hybrid timber-glass beam. It is a I-shaped section and consists of timber flanges and glass web bonded with an adhesive.

Please look at the attached diagram - Force versus vertical deformation. Until an initial crack it is almost perfectly linear. But what happens after the glass failure? What could be the reason that the force changes like a wave?

 

 

Nonlinear Size-Dependent Analysis of Elastic Tiny-Bodies

Submitted by M. Shaat on

Many researchers have studied the effect of surface energy on the
elastic behavior of nano-structural elements based on Gurtin and Murdoch surface
model. Many of them, however, assumed that the surface energy depends only on
the 2D symmetric infinitesimal surface strains and neglects the second-order
products of surface strains/displacement gradients. Moreover, there are some
researchers assumed that the surface energy is independent on infinitesimal
rotation tensor and neglected all rotation

Kinetic Energy-Based Temperature Computation in Non-Equilibrium Molecular Dynamics Simulation

Submitted by Bin Liu on

      The velocities of atoms in MD simulation are not objective quantities, which depend on the choice of the reference frame and sample size. In our previous study (node/3181), we discussed how to overcome this non-objectivity and compute the atomic stress objectively. In this blog, our newly published paper on temperature computation is attached, and the abstract is as follows.
