Question

The flow stress (in mpa) of a materi l a is given by 0 1 where ε is true strain the young's modulus of 0.1 σ = 500ε where ε is true strain. The young s modulus of elasticity of the material is 200 gpa. A block of thickness thickness 100 mm made of this material material is compressed to 95 mm thickness and then the load is removed. The fi l na di i mens on of the bl k oc (in mm) is

Answer 1

The flow stress (in MPa) of a material is given by

σ=500ε0.1σ=500ε0.1,

Where εε is true strain. The Young’s modulus of elasticity of the material is 200 GPa. A block of thickness 100 mm made of this material is compressed to 95 mm thickness and then the load is removed. The final dimension of the block (in mm) is ____

Answer : 95.14 to 95.20
