2 post-doc positions available at Northwestern University – Mechanics and Energy Lab

Dear Colleagues,


with this message, I would like to advertise 2 post-doctoral research positions at the intersection of electrochemistry and mechanics of materials in my lab at Northwestern University. The two post-doctoral projects will specifically focus on the influence of electrodepositions on the structure, properties, and behavior of soils (project 1) and concrete (project 2).


Material Testing: Crucial Step in Bridge Development & Engineering Design

Bridge failures underscore the importance of rigorous material testing. The collapse of the incomplete pedestrian bridge at Florida International University on March 2018 is an example where design errors led to growing cracks as described by OSHA.

Although material failure is not the sole reason for bridge failures, it is a crucial step for selecting the right materials, bridge design analysis, and construction testing.

PhD position - Development of mesoscale hydro-chemo-mechanical (HMC) modeling approach for concrete deterioration.


The main aim of this project is to develop a robust computational framework for investigating the hydro-chemo-mechanical aspect of concrete carbonation at meso-scale.


Automation vs. Manual Control in Concrete Testing

Concrete is one of the most widely used materials around the world. The construction industry is often involved in a wide array of testing which requires a variety of testing equipment. In addition to simple compression testing, testing standards such as ASTM C39, ASTM C109, ASTM C469, ASTM C1609 are among the test methods that can be followed to measure the mechanical properties of a concrete specimen. This blog post covers the mechanical testing of concrete in lab environments, its automation, and ways of achieving it.

Eigenerosion for static and dynamic brittle fracture

In contrast to many numerical methods, the eigenerosion approach yields a convenient description of fracture handled in the postprocessing part of a Finite Element Analysis (FEA). Its fully energetic formulation avoids the introduction of extra degrees of freedom to model fracture propagation. Following previous works on eigenerosion, in this publication, a modified formulation of eigenfracture it is introduced, where it is distinguished between compression and tension loaded state.

Damage plasticity model for concrete failure CDPM2

Those involved in the modelling of the failure of plain/reinforced concrete using damage and plasticity might be interested in our webpage

which we have created to support our concrete damage plasticity model CDPM(2) in LS-DYNA. You can find there a number of example input files, reports and our implementation of the model in the form of a user subroutine.

How obtain tension strain concrete(σt0) in damaged plasticity model in ABAQUS?

hello engineers

i need help about concrete damaged plasticity

fo example :

if Compressive stress (Fu)= 51.2 MPa

and tension stress (σ t)=0.3 x 51.2^(2/3)=4.136

1)why (σ t) is 2.36 in picture(uploaded)?

2)what is tension strain ? and how? i cant understand.

i cant obtain εt = total tensile strain.

how obtain εcr ?

please help

Modelling time dependent concrete properties in ABAQUS

I am
carrying out a non-linear analysis of a concrete section subjected to construction
loading. I am looking to model the time-dependent effects of the material
properties as well as creep and shrinkage properties of concrete. In the ABAQUS
manual it states the General Static procedure
cannot be used to model time dependent effects. Naturally the Riks Method would be ideal to account of
the non-linear effects however it doesn’t allow for the use of multiple steps in
the analysis which is necessary to model the various stages of construction

Cracking of the concrete cover due to reinforcement corrosion

Dear all,

 Our paper titled "Cracking of the concrete cover due to reinforcement corrosion: A two-dimensional lattice model study"
 has just been published in Construction and Building Materials. It deals with numerical modelling of cracking of the concrete cover as a consequence of reinforcement corrosion, based on the Delft lattice model framework. Registered subscribers can download the article at:

Elastic material in abaqus

Choose a channel featured in the header of iMechanica: 

Dear all,

I am using Abaqus to model concrete as an elastic material. However, the failure criteria available in the software is only for 2D elements and are dominated by a maximum normal stress (fail stress option) or normal strain (fail strain option) value.

I was wondering if anyone would know how to model concrete as an elastic material following "theory of elasticity" and failing by a maximum TENSILE strain value in any of the three directions given a material's point.
