How to use non-dimensional form in open source codes instead of Units
I am using an open source FEM platform, which requires you to convert your equation system to non-dimensional form. So, there are no units specified for the parameters in the problem. If you use compatible input units, you should expect the output in matching unit - just like one would do in a normal python or C++ code for solving physical problems. I have an elasto-plastic dynamic problem to solve, and these are the parameters for the Drucker-Prager Soil Model for soft clay.

Rectangular frame calculation by beam finite elements
Beam elements are very widely used in structural engineering. Here we consider the methodology for calculating the rectangular frames with articulated or rigid nodes. The load is evenly distributed and concentrated. The result is exactly the same with the results of the method of force and displacement method. A practical example of the calculation of the frame. The input data for the program will be the number of items and the number of degrees of freedom, geometrical and physical characteristics as well as the degrees of freedom of information for each item.
Multiple Faculty Positions in the College of Engineering at UW-Madison
The College of Engineering at the University of Wisconsin-Madison seeks faculty candidates for up to four tenure-track faculty positions in the mechanics of solids and soft materials. Candidates excelling in experiments, theory, computational modeling, or any combination of these approaches are sought. Particular application areas of interest include (but are not limited to) cellular and tissue biomechanics, additive manufacturing, microelectronics, energy production/storage, and response of infrastructure to man-made and natural hazards.
Tensile instability in a thick elastic body
A range of instabilities can occur in soft bodies that undergo large deformation. While most of them arise under compressive forces, it has previously been shown analytically that a tensile instability can occur in an elastic block subjected to equitriaxial tension. Guided by this result, we conducted centimeter-scale experiments on thick elastomeric samples under generalized plane strain conditions and observed for the first time this elastic tensile instability.
Mixed assumed-strain finite element model for laminates
Fibre-reinforced plates and shells are finding an increasing interest in engineering applications; in most cases dynamic phenomena need to be taken into account. Consequently, effective and robust computational tools are sought in order to provide reliable results for the analysis of such structural models. In this paper the mixed assumed-strain laminated plate element, previously used for static analyses, has been extended to the dynamic realm. This model is derived within the framework of the so-called First-order Shear Deformation Theory (FSDT).
