What is the possible reason for increase in compressive stregth of concrete upto 14 days and decrease subsequently when it is cured in sea water?

I have conducted a few tests on concretes mixed and cured in sea water. I observed that the strength increased for the first 14 days but decreased there after. I also repeated the tests for OPC,...

How can we check if a non-linear multi-variable (more than 4 variables) function with constraints is a convex function or a concave function?

I am not a mathematician and so is there any program or tool for the same? I require it before i adopt RGM for this function for optimization.

How can we interpret the results of durability tests on concrete like sulphate attack or acid attack on concrete say loss of strength or weight?

Generally durability of concrete is determined by curing concrete in 5% or so solutions of H2SO4 or HCl and the loss of strength and weight is determined. I guess they only give the relative...

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,
