B=\(\frac{1}{x_2-x_1}\)[-1 1] is an ___________
a) Strain matrix
b) Element-strain displacement matrix
c) Displacement matrix
d) Elemental matrix
Answer: b
Explanation: ε=Bq
Here B is element strain displacement matrix. Use of linear shape functions results in a constant B matrix. Hence, in a constant strain within the element. The stress from Hooke’s law is
σ=EBq.
