Second law of thermodynamics and Configurational Mechanics
Hello,
I have been reading up a lot on "Configurational Mechanics" and frankly i came up with a lot of questions. I am not skeptical at all about it, it just that many things are not clear to me.
Effect of Residual stresses on the Interfacial Fracture Toughness of polymer/Metal Interface
When a bi-material sample for the characterization of interfacial fracture toughness is manufactured, the sample is not usually stress-free at room temperature. If an interface between a metallic substrate and a polymeric adhesive is considered, there are essentially two sources of residual stresses for a dry sample at room temperature:
1- The mismatch between the Coefficient of Thermal Expansion (CTE) of adhesive and substrate induces a concave or convex warpage, depending on the CTE values of the two materials.
JOURNAL CLUB DEC 1 08: CYBER-ENABLED PREDICTIVE SCIENCE-BASED CONTINUUM MECHANICS FOR MULTISCALE FRACTURE PROCESS DISCOVERY
The key to developing materials against failure under extreme environments is the understanding of the interplay between the various physical scales present, from the atomic level interactions, to the microstructural composition and the macroscale behavior. The ability to do this requires new methods that can be used to predict macroscale properties accurately based on microstructures and nanostructures without resorting to empiricism.
force on dislocations
Hi, how the Peach-Koelher force acts on a dislocation?, I understand when the resolved shear stress acts on a dislocation. But not quite the term that provokes climb on an edge dislocation...
any theories on the stress wave propagation in concrete?
does anyone know any current theories on the stress wave propagation in a complex media(such as concrete or rock).(1D sphere wave or complex)
all i see is the simulation with a complex constitutive model. but i think it`s not perfect.
hope for your help

Elasticity "Exact" Solutions for Plates
Many of you developed Finite Element codes. These codes are usually quite complex. So you all know the importance of testing your results to see if what you programmed makes sense. The usual approach is to compare your FEM program with somethig already published. With this in mind, I designed a series of "lectures" on the topic of elasticity solutions for plates. You can find the details in
