Contact mechanics has its application in many engineering problems. No one can walk
without frictional contact, and no car would move for the same reason. Hence contact …

We present an objective, singularity-free, path independent, numerically robust and efficient
geometrically non-linear Reissner-Mindlin shell finite element formulation. The formulation is …

Computational aspects of a geometrically exact stress resultant model presented in Part I of
this work are considered in detail. In particular, by exploiting the underlying geometric …

Computational welding mechanics (CWM) provides an important technique for modelling
welding processes. Welding simulations are a key tool in improving the design and control …

Recent years have seen a research revival in structural stability analysis. This renewed
interest stems from a paradigm shift regarding the role of buckling instabilities in engineering …

The paper investigates instability phenomena in the context of homogenization-based micro-
to-macro transitions of heterogeneous materials at finite strains. This covers structural …

In spite of spectacular development of reticulated shells, at least one problem has not yet
been solved satisfactorily and that is the problem of buckling. The instability of isolated …

For the evaluation of the imperfection-sensitivity of elastic and elastic-plastic shells a fully
nonlinear finite-element-method has been developed that directly gives the …

In this work, a direct physics-informed neural network (DPINN) is first proposed to analyze
the stability of truss structures that incremental-iterative algorithm is completely removed …
