Dependence of fracture energy of ceramic on loading condition?

engineering fracture mechanics

dynamic fracture

ceramics

Literature suggests that the fracture strength of the ceramic tends to be higher in a dynamic loading condition than in static condition. This relates to the increase in the fracture energy in dynamic processes. Literature refers to an inelastic response prior to failure (Hugoniot elastic limit) the reason behind increased strength. Can anyone explain the phenomenon in a more lucid way, or guide me to an appropriate reference to understand this?

This video shows how to write and implement a simple user material in ABAQUS. I hope it helps.

Stresses go beyond yield limit in perfecly-plastic model...

perfect-plasticity

perfectly plastic material

Hi all,

I have a problem with perfect-plasticity material model in Abaqus. I this simple 2D analysis, I am modeling a beam fixed at both ends and applying temperature loading on it that will cause yielding. The material model is perfectly plastic with,

*PLASTIC

4.85 E8, 0.0

The problem is, stresses go beyond yield limit (4.85 E8) which should not be the case for the perfectly-plastic material model. I would appreciate any comment/help/suggestion.

Regards,
