SURFACE TEMPERATURE MODEL - ANALYSIS OF EARTH`S CRUST RESPONSE TO CHANGES IN SURFACE TEMPERATURE

Abstract

: The article has focused on issues from the fields of geophysics and geomechanics, using methods, approaches, skills, and experiences from applied mechanics. Its core topic is the investigation of the influence of exogenous factors on phenomena occurring within the Earth’s crust. Based on that, the model was created to explore an exogenous influence - cyclic temperature variation (daily and annual). The article shows statistical calculations for the creation of stochastic models for the process of strain and stress on the surface of the Earth’s crust. The outputs of this model are in accordance with measurements of temperatures under the Earth’s surface, so the results can be considered relevant. The model showed that changes in stress due to cyclic changes in surface temperatures could reach values of up to 50 MPa. a 2D model on parts of the and Earth's crust in (Finite Element Method FEM). The results are processed values and trends of the and stress-deformation field in the whole of the Earth's crust. The
