A new method of plastic limit analysis for rectangular plates
Based on a new element model of solid body, the plastic limit analysis of plate is carried out. The new element model is a truss composed of 24 bars. Taking the simply supported square plate and rectangular plate under uniform load as an example, by comparing the new element method with the classical plastic limit analysis theory, it can be found that the limit load and the distribution of plastic zone obtained by the two methods are in good agreement.
A new model for elasto-plastic analysis of steel
This is a beautiful, unparalleled elastoplastic model for plastic materials.
Based on the equivalent stress and deformation of regular hexahedron microelement and truss element, a new truss element model is presented. It can be used to solve the elasto-plastic plane stress problem and spatial problem of steel. Through a large number of examples, the new element model can be found to have good accuracy.
A new method of plastic limit analysis for beams and frames
The plastic limit of beams and frames have analyzed by using a new truss element model of solid bodies, compared with the plastic limit analysis method, it can be found that the limit load of the two methods are in good agreement.

Two PhD positions available at Multiscale Computational Mechanics Lab at Vanderbilt University
We are seeking two doctoral students to join the Multiscale Computational Mechanics Laboratory (MCML) at Vanderbilt University beginning either Fall 2023 or Spring 2024. The research areas span multiscale computational mechanics and computing, and are briefly described below. Candidates must also have a strong general interest (prior experience is a plus) in computational mathematics, mechanics, modeling and simulation and computer programming.
The specific research areas as follows:
Postdoc Opening at the PSAAP Multidisciplinary Simulation Center, CU Boulder
We are currently looking for a Postdoctoral Research Associate. The position can start immediately but US citizenship is preferred.
Postdoc Position in Dynamic Fracture of Materials at Czech Technical University in Prague
Postdoctoral Research Assistant in Dynamic Fracture of Materials
We are seeking a highly talented and motivated researcher to work within our strong research group “Dynamics of material fracture” oriented at experimental and numerical investigation of mechanical response and failure of materials at high strain rates. This post is based in Prague, Czech Republic and is available for 2 years.
The detailed description how-to apply for the position and the application form can be found here:
Discussion of fracture paper #37 - A Novel Approach Improving Mode I+III Cohesive Zone Modelling
The advantage of simplicity is that mechanics and physics can be understood and predicted just by using pen and paper. In the end, numerics may have to be used but then you should already have a pretty good idea of what happens. The other way around, starting with numerics and a limited toolbox of models will seldom lead to anything new.

Postdoc Position in in situ SEM mechanical testing at Johns Hopkins University
I have an open postdoc position with focus on in situ SEM testing coupled with laser interferometry to characterize crack initiation in complex alloys. The applicant is expected to have strong background in mechanics of alloys and has expertise with in situ SEM testing. Strong hands-on experiences in budling/designing new experiments and/or experiences with lasers would be a strong plus.
