A question has arised when I read a book about fracture mechanics recently.
This question is about the calculation of potential energy in "fixed-grips" (prescribed displacement) and "dead-load" (prescribed displacement).
Hi,
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.
I'm a MSc (Applied Math) student modelling vibrating bridge hanger cables using corotational method. I'm interested in chatting with anyone using this method, especially for cables/beams but also other contexts. Thanks, John.
Dear Mechanical Engineers,
It's my pleasure to be one of your group. I have a question in Abaqus Explicit and all my friends recommended me to as iMechanica as the explicit Abaqus is more popular to you than us as civil engineers.
Please find a phd position at Ecole des Mines de Douai related to the fatigue of composite materials.
This paper studies the dynamic behavior of a dielectric elastomer balloon subject to a combination of pressure and voltage. When the pressure and voltage are static, the balloon may reach a state of equilibrium. We determine the stability of the state of equilibrium, and calculate the natural frequency of the small-amplitude oscillation around the state of equilibrium. When the voltage is sinusoidal, the balloon resonates at multiple frequencies of excitation, giving rise to superharmonic, harmonic, and subharmonic responses. When the frequency of excitation varies c
