How a "surface texture" property can be simulated on a coarse aggregate, numerically ?

I am trying to develop a numerical aggregate model for a concrete specimen, to study the behavior of mechanical properties due to the variations of aggregate surface texture (same as surface...

How to find the torsional vulnerability of a 2-storey building based on center of resistance?

This 2 storey building's layout is attached in the attachments. Here the architect wants to remove the column C (in the ground floor) and add a wall only from C to D. So this wall exist in the...

How do I select a metal for the anode in accelerated corrosion process using chlorides?

Hi all, I am trying to use accelerated chloride corrosion process for reinforced concrete. For this purpose I use stainless steel for the cathode. But if I use the reinforcement as anode, it will...

What is the relationship of corrosion rate Pr (micrometer/year) and the mass loss Wl(g) based on Faraday's Law of Corrosion?

In a paper, I saw Pr = (1.116x10^7 x WL)/(AxT) Pr = corrosion rate (um/year) WL= weight loss (g) A = Surface area (cm^2) T = Time elapsed (Hours) Can someone help me to derive this equation? Thank...

Could someone recommend an experimental method to find the Chloride Threshold Value for different types of steel due to corrosion?

I am a researcher who studies on concrete durability in terms of corrosion effects due to chloride attack. Chloride threshold value has become a predominant factor in predicting the life of the RC...

Is anyone capable of providing a realistic range for the fracture energy of ITZ in concrete (in both tension and compression)?

In the concrete, interfacial transition zone (ITZ) has different fracture material properties than the aggregate or the cement paste matrix. In studying about the fracture propagation, ITZ will be...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
