Hi everyone, Have not seen this question raised and I need help. This in reference to the material in Chapter 18 of NR Book under (integral equations with singular kernel). I have to solve integral equation with a Cauchy-type singularity (occurs in line-contact problems, see Johnson K, Contact Mechanics, 1985). The integral is:
I(x) = integral(f(x')W(x,x')dx' , x'=a...b)
where W(x,x') looks like 1/(x'-x), x is within (a,b) and f(x) is well behaved.
I am now in the process of looking at this and reading the NR book. I want to do this numerically perhaps by modifying the code given in the NR Book. Has anyone done this? Any helpful suggestions would be appreciated. Hope the Authors can address this specific type of problem may be by example.
Thank you.
