HomeWork 1 Problem 1 Self Description
I am Ashwani Kumar Goel, currently pursuing my Ph.D. from Engineering Mechanics Department, University of Nebraska Lincoln. I am from India. I have taken my Bachelors degree in Mechanical Engineering from HBTI, Kanpur,India and my Masters degree in Applied Mechanics from IIT, Delhi, India. I have taken lots of courses related to solid mechanics starting from my undergraduation. I have taken strength of materials ,applied mechanics, mechanics of solids during my undergraduate degree and applied elasticity, theory of plasticity, theory of plates and shells, continuum mechanics, linear viscoelasticity during my graduate degree. The group I work in focuses on theoretical, computational and experimental methods for the modeling and analysis of materials and the simulation of their response. I have been part of this group for about two and half years and focusing on theoretical and computational methods to extract material characteristics from novel experimental methods and in the implementation of these characteristics into simulations.
My strengths related to this course is that I have studied variety of subjects related to solid mechanics and can use my knowledge to calculate the response of the material. I can also use finite element tool to analyze the structures. I believe that I can use these two tools to get a good understanding of fracture mechanics. My weakness is that till yet I have not performed any fracture analysis using finite element software. As I am working on theoretical and computational aspects to characterize the material, so I want to understand the governing equations and how the effect of fracture can effect those equations. I also want to analyze numerous specific problems requiring application of fracture criteria and comment on their validity. I want to get aware of how can we perform fracture mechanics analysis using finite element tool like aqaqus so that if I put any user material constitutive equation in a software it could provide me a quantitative answers about cracks.

Hi aswani kumar i am
Hi aswani kumar
i am ravitej, doing my mtech in IIT kanpur. from ur posting i can guess that u had great knowlwdge in theoritical concepts of strength of materials.i want to ask a doubt regading strength of materials.
i want the mid point deflection in case of "four point bend test" on a
specimen of length 140mm, width of 40mm and thickness of 10mm.
Problem is that, beam theory is valid if the cross-sectional
dimensions are less than axial dimensions. Here this condition is
violated. i had modeled the specimen in Abaqus and the diffection at
mid point is almost double that of the actual diffection calculated
from beam theory.
how can i find the theoritical difflection at mid point in this case?
i had one option, using timoshenko beam theory and applying larger
deflection theory. will it be a reasonable approximation in this case?
please help me in this aspect.
