i am trying to develop a matlab program to calculate the natural frequency anf the model shapes for beams
using the finite element method , as i will need to change the stiffness in the beam sections to model cracks.
i am sure there an easy ready method to perform this , i am happy if some one provided me with the method or the basic code
What is meant by wave number?. What is the allowable standard power spectral density for road profiles?
Dear members,
I need some information about the implication or significance of J1 and J2 in granular materials not mathematical represantation which I have.Your feedback will be highly appreciated.Thanks in advance.
P = Mean stress or Hydrostatic stress = (σ11 + σ22+ σ33)/3
J1 = -3 * p
I am in the process of applying for a PhD in computational solid mechanics in the US and I am about to take the GRE. Well I have been kind of busy at my work and didn't really get time to study the word list.
My question is, how much weight does the verbal part have in admission/fellowship/assistantship decisions? If I have really good GPA's and research experience with enthusiastic refrees, can I still make it with medicore results on the verbal part?
I am a abaqus beginer, I want to know how to analyse creep of tubular component in abaqus. If you have any material regarding this kindly mail me. I need it for my project work.
See attachment for ES 240 lecture notes on plasticity.
I'm teaching Applied Mathematics 105a this semester. The main content of the course is complex analysis. The course is taken mainly by undergraduate students in Engineering, Physics, and Applied Mathematics. There are about 70 people in the class, which makes it the largest class I have taught in the last 10 years. I have never taught a course on complex analysis before, but have used complex analysis in my research, and have taught the method of complex variables in my graduate course on elasticity.
please help me regarding UPPER BOUND ANALYSIS for KINEMATICALLY ADMISSIBLE SOLUTION.AND how can i ploat the hodograph for any kind of indentation..try to help me with the figures..as soon as possible guys.
