How can I determine if this metal flange is wide enough to support a load without permanently deforming?
I'm designing a sheet metal panel for an enclosure, which will be built of 1.6mm thick 5052 H32 Aluminum. The panel looks like this: The panel will fit inside a four-sided frame. The top is fitted ...

Apparent elastic modulus formula and meaning of squared Poisson's ratio
I come from a maths background but I am currently engaged in a project which involves viscoelasticity modelling, so stress and strain come up a lot. In some papers I've read (here and here) people ...

Is there any special coating or paint that will strongly bond to an automobile tire's tread and can be driven on?
I would like to know if there is any special coating or special paint that can be applied to the tread of an automobile tire, strongly bonding to it, and which is strong enough and durable enough to ...

How can I anchor a rubber sheet that will be stretched?
I am designing a cylindrical container that will be filled with water. One end of the container will be solid with flow port and the other end will be a 3mm rubber sheet. I want to oscillate the ...

Why are Lamé parameters different in two dimensions?
The Wikipedia article has a completely separate table for Lamé parameter conversions in the 2D case. Philosophically, why is there even a different table for 2D if these parameters are meant to ...

Strain As A Function of Deflection of a Hollow Cylinder
I should think that there would be a direct correlation of strain to deflection of a hollow thin-walled cylinder, but I've seen nothing as of yet. I must be missing something. For example, let's say I ...

Is there a rubber material with an elastic modulus lower than 1 MPa?
I'm looking for an elastic material (e.g., a rubber), whose tangential elastic modulus E is lower than 1 MPa (0.5 MPa would be enough). Anyone has an idea of which kind of rubber could fit this ...

What is the difference between Hooke's Law and Young's Modulus?
In the elastic region where stress is proportional to strain up to elastic limit which is we call Young's Modulus (E). My question is if that is E, then what is Hooke's Law (K=F/x spring stiffness). I ...

Difference between Stiffness (K) and Modulus of Elasticity (E)?
Stiffness (F=Kx) is the extent to which an object resists deformation in response to an applied force. Elastic Modulus (E=Stress/Strain) is a quantity that measures an object or substance's resistance ...

What is the physical reasoning behind metal becoming stronger and harder if heat treated?
I was wondering that if a proper process of heat treatment (heating to a temperature above upper critical temperature, then soaking and then quenching) is applied to a metal like steel, then what ...

Is there any difference between an-elastic and visco-elastic materials?
Most of the sources that I had read about either talks about anelasticity or viscoelasticity, they don't compare both. From what I have read so far ,both anelastic and viscoelastic materials are the ...
