Strain transformation

Question 1

What is plane strain?

Answer 1

A method used to turn 3-D stress analysis problems into 2-D problems, by assuming small stresses in one direction are equal to zero.

Question 2

In a case of plane stress what stress values are equal to 0?

Answer 2

σzz=τxz=τyz=0

σxx,σyy,τxy may not equal zero

Question 3

In a case of plane stress what are the strain values that are equal to 0?

Answer 3

γxz=γyz=0

εxx,εyy,εzz,γxy may not

Question 4

In a case of plane strain what are the stresses that are equal to zero?

Answer 4

τxz=τyz=0

εxx,εyy,γzy may not

Question 5

In a case of plane strain what are the strains that are equal to zero?

Answer 5

εzz=γxz=γyz=0

εxx,εyy,εxy may not
