Blackmax, when you say strain distribution in the ceramic, I think you mean from the joint up, in the Y direction right? I understand that the shear strain in the two joints should be the same. So it is the same as that of the brick. What is the relation between F1 and F2 in the attached...

Sure ! but we know already the strain. The problem is the ceramic sensor behavior and modeling.

The intention is to measure the brick deformation by the sensor. The brick does not fracture and the sensor reads a smaller strain than expected (P/A)/Eb.

From the sensor reading, The strain in the sensor is 1/10th the calculated strain on the brick. I think in this scenario the sensor has shear strain.

Hello Blackmax, The ceramic piece is a thick film sensor. The result of strain calculated this way is much bigger from the sensor reading. I think the relationship you suggest is valid if the cross sectional areas of ceramic and brick is the same. It seems that some geometrical factor is...

Hi Experts, I posted this elsewhere and got no answer. May be somebody here can help. I have a piece of ceramic(E=270000 N/mm2) glued with a two component epoxy to another much softer material like brick ( E=14000 N/mm2). The brick is much bigger than ceramic as in the attached diagram...

Thank you desrtfox , I have sensors attached to the internal side and I could calculate their response and it corresponds almost to the experimental results. regards Jabir

Hi experts, How can I find the strain long a fixed column which has decentralized load like attached figure. I would like to find the strain at any point X long the internal side of a rectangular column. Thanks for any help

Hi everybody, I have the following problem: I use two component epoxy to attach ceramic (270000 N/mm2) to a brick (14000 N/mm2). The ceramic piece is very thin and small with respect to the brick. When the brick is subject to compressive stress, the brick will have a strain that follows...
