for a perfect elastic body the stress strain graph is always linear, meaning stress is always proportional to the strain through a constant i.e., the young's modulus of elasticity which is proportional to the slope of the linear property of the stress strain graph. if a body is ideally plastic it means to have infinite linear line from the centre of the stress strain graph. A linear line like this could have any slope=tan θ. this linear line could have any angle meaning any slope can values between 1 and 0 implying that young's modulus could be any value.

Whats is young's modulus?
Young’s Modulus (also referred to as the Elastic Modulus or Tensile Modulus), is a measure of mechanical properties of linear elastic solids like rods, wires, and such. Other numbers measure the elastic properties of a material, like Bulk modulus and shear modulus, but the value of Young’s Modulus is most commonly used. This is because it gives us information about the tensile elasticity of a material (ability to deform along an axis). Young’s modulus describes the relationship between stress (force per unit area) and strain (proportional deformation in an object). The Young’s modulus is named after the British scientist Thomas Young. A solid object deforms when a particular load is applied to it. The body regains its original shape when the pressure is removed if the object is elastic. Many materials are not linear and elastic beyond a small amount of deformation. The constant Young’s modulus applies only to linear elastic substances.

Metric unit of young's modulus?
Young's modulus is defined as the ration of stress to strain for a given material below the limit of proportionality (the elastic limit). So Young's modulus is calculated by the formula: Stress/Strain is equal to young's modulus. Stress is defined as the force per unit area of cross-section below the limit of proportionality. So the formula is: Force (in newtons)/ Cross sectional area (in square metres). This would give the units Newtons per square metre which is written Nm-2 which is exactly the same as the Pascal (Pa); either can be used. Strain is defined as the fractional change in length produced when a body is subjected to stress. It's formula is: Change in length produced (in metres)/ Original legth (in metres). There are no units as it is a ratio of two values that have the same unit. So Young's Modulus has the formula: (Force/area)/(change in length/original length). This can be simplified to Stress/Strain (the amount of stress a body has to undergo to produce a certain amount of strain. The unit for stress is the Pascal (Pa) and there are no units for strain so overall, the unit for Young's Modulus is the Pascal (Pa) or Nm-2.

Nobody is perfect.
Is the bulk modulus of elasticity increases with pressure?
Yes, the bulk modulus of elasticity increases with pressure. The bulk modulus measures the resistance of a material to changes in volume under applied pressure. As pressure increases, the material becomes less compressible and therefore the bulk modulus increases.
Can Thermal Stress of a body be zero?
No. Thermal stress of a body can never be zero. It is so because for a given body, Young's modulus of it can't be zero, linear expansivity of it can't be zero and for a given temperature change, also the change in temperature can't be zero. But for some bodies made of substances like inver, whose thermal expansivity is very very small, the stress is negligible and can be neglected.
Is there any perfect black body in the universe?
No. The black body is an "ideal thing" or a construct, and there isn't anything that "perfect" in nature.
