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.

Hello every one,
I am modeling a core (C shape) subjected to lateral load. I used embeded region constraint to contact steel bars and stirrups to the solid core. Then i want to apply the load at one end of core, but i need to contact all points in this end with a diaphragm to take the effect of the slab which aren't modeled. But i thing that ABAQUS doesn't permit to use two constraints at the same point. So what can i do to constrain the steel bars to core and also to constrain all points at one end with a diaphragm.
Thanks in advance
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.

As an example, here we discuss implant-associated infection from the mechanics point of view on bacteria adhesion affected by the biomaterial surface roughness:
1. Implant-associated infection, a leading cause of failure in many biomedical devices, is caused by adhesion of bacteria to the surface of biomaterials. Implant-associated infection is difficult to treat, for example, joint replacement infections may occur deep around the artificial implants.
The relationship between the strains and stresses will be considered based on the premise that for every increment of load deformation occurs, consisting of two parts - the elastic and plastic
The program of calculation by finite element method. Basis of its program described in the work [Siratori, T. Miesi, and Kh. Matsushita,Numerical Mechanics of Fracture], which has implemented the theory of plastic flow and deformation theory. The plastic problem is solved by the incremental method of loading, with each increment of load shifted one element to the plastic zone.
