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.

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.

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.

Composite materials in extreme environments

Applications are invited for a Ph.D. studentship in the Departments of Aeronautics. The successful candidate will have the opportunity to conduct cutting-edge research in the field of composite materials.

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.
