Can anybody recommend some papers/books that discuss how to caculate thermal induced warpage of lamianted composite materials? Paper/books with detial caculation/derivation process are preferred. Thanks a lot!
In this paper we formulate a geometric theory of thermal stresses.
Given a temperature distribution, we associate a Riemannian
material manifold to the body, with a metric that explicitly
depends on the temperature distribution. A change of temperature
corresponds to a change of the material metric. In this sense, a
temperature change is a concrete example of the so-called
referential evolutions. We also make a concrete connection between
our geometric point of view and the multiplicative decomposition
of deformation gradient into thermal and elastic parts. We study
the stress-free temperature distributions of the
finite-deformation theory using curvature tensor of the material
I am new to Abaqus. I am working on a research topic where in I need to study the transient thermal stresses, strains arised due to heating a body by thermal radiation. From the user's manual I understood that I need to use "Sequentially coupled thermal-stress analysis" for my model.
I want the sample surface to be heated at a specific rate (say 20 C/min). I am not able to figure out how to set this condition when using "surface radiation" heat transfer or may be at what rate should I change my ambient temperature for the body surface to get heated at the specific rate.
Can anyone please help me in this regard?
Thanks in advance.
I am having confusions about the concepts of thermal stresses of an un-constrained elastic body when heated/cooled.
Let's say if I have an elastic body of an arbitrary geometry. If I subject it to a uniform temperature change without any constraints, then there will no thermal stresses at the end of the analysis. I guess I am right till here.
